SHANE DUFFY has seized the opportunity to re-establish himself at the heart of Brighton’s defence to the obvious delight of the manager who appeared to have shunned him.

With injury sidelining Dan Burn and Covid-19 isolation protocol ruling out Joel Veltman, Duffy stepped up with a solid performance in the season-opener at Burnley, and a goalscoring return to the Amex in the 2-0 win over Watford.

“It was a fantastic header from Duffy, he’s a monster in the box,” boss Graham Potter told the BBC after the televised Watford match. “He is so big and strong to stop – it was a great goal.”

Duffy’s form has been a reminder of the solid centre-back partnership he formed with Lewis Dunk as the bedrock of Brighton’s promotion from the Championship in 2017.

Although a metatarsal injury in a 3-0 defeat at Nottingham Forest meant he missed out on the run-in, Duffy was obviously confident of being restored to the line-up when the Premier League season got under way.

“I’m looking forward to going back to Everton to see a few mates but they’re all going to be big games,” Duffy said in a matchday programme article. “I feel more ready for it than I was four or five years ago at Everton, and I deserve another crack at it, but I know I’ve got to work hard.”

While additions to the squad were to be expected as the Albion sought to stay among exalted company, the Duffy-Dunk pairing at the back didn’t look much like being broken up. Certainly not under Chris Hughton.

Happy with his mainstays at the heart of the defence, Hughton allowed Connor Goldson to leave for Glasgow Rangers and Uwe Hünemeier to return to Germany and Duffy was comfortable alongside Dunk as Albion retained their top division status. And so it remained for Albion’s two first two seasons back amongst the elite.

But when Potter replaced the popular Hughton in 2019, it soon became apparent Duffy didn’t fit the mould of the sort of ball-playing centre-back he wanted in the side.

Although he started the season under Potter, his place was gradually taken over by big money signing Adam Webster. Duffy invariably ended up warming the bench and at the start of the 2020-21 season, with Ben White preferred alongside Dunk and Webster, he jumped at the chance to go on loan to Glasgow giants Celtic, the team he’d supported as a boy.

Unfortunately, it didn’t turn out to be quite the dream move Duffy had hoped for, with criticism arrowing in from all quarters as the Republic of Ireland international underwhelmed in the centre of the Hoops defence, and Celtic could only watch as city rivals Rangers won the Scottish title.

Doubtless the irony wasn’t lost on Duffy that his first match back in a Seagulls shirt saw him up against Rangers in a pre-season friendly, when the home fans ensured he was given a ‘warm’ reception.

But let’s go back to where it all started.

Born in Derry, Northern Ireland, on 1 January 1992, Duffy was playing for Northern Ireland Under-16s against England in the Victory Shield when he caught the eye of watching Everton boss David Moyes.

Duffy had been playing for his local side, Foyle Harps, at the time and, although Arsenal took him on trial and offered him a scholarship, Everton invited him to train with them and offered him a professional contract immediately.

“Of the two clubs, I just had a good feeling about Everton; obviously it was more of a family club, and there’s also the Irish connection with the city of Liverpool, so it was easy for me to settle in,” Duffy told the matchday programme.

In his second season at Goodison Park, he made his first team debut aged just 17 in a Europa League match against AEK Athens.

“David Moyes handed me my debut and I owe him a lot because he always had belief in me, whereas I could have gone somewhere else and maybe ended up back in Ireland,” he said. “I was raw as I hadn’t been with an academy before, but he was patient with me, as were all the coaches, and I came through the youth team and reserves before I got my break in the Europa League and then later in the Premier League.”

Duffy played against Brighton when the third-tier club’s youngsters (with Dunk in defence) acquitted themselves brilliantly in the fourth round of the FA Youth Cup against Everton at the Withdean on 21 January 2010 before eventually losing 2-0. The programme pen picture said of him: “Strong in the tackle and dependable in the air, Shane is considered a ball-playing defender.”

Duffy recalled: “I’d just turned 18 and had recently broken into the Everton team in the Europa League. I do remember Dunky a little bit because we were marking each other at corners.”

A month after his visit to Withdean, Duffy decided to switch allegiance to the Republic having previously captained Northern Ireland’s Under-19s. It came just as he was selected for the full international squad to face Albania in a friendly in Tirana where he was expected to receive his first cap in the absence of captain Aaron Hughes (who later spent a season with Brighton) and Chris Baird.

Disappointed Northern Ireland boss Nigel Worthington told The Guardian: “There is a loophole where a player can walk away after a lot of time and investment has gone in. Until it is resolved, that’s where we are. Shane has represented Northern Ireland all the way through from a very early age to the Under-21s.

“I am a big admirer of Shane. I like him as a player and a lot of work has gone in with different coaches. I am disappointed with the situation as he is going to be a very good player. Shane has decided, after discussing the matter with his family, to represent the Republic. As a manager, I have got to respect that.”

Duffy, who had close family ties to Donegal in the Republic, said the decision to switch his allegiance from Northern Ireland was the right thing to do to help his international career.

Speaking to evertontv, Duffy said:“It was difficult for me to leave because of what they’ve done for me in Northern Ireland since I was young. They brought me through the ranks which gave me the chance to come to Everton.

“It was hard to leave all the coaches and all the players, but it was always a case of wanting to come to my own country. I spoke to a couple of people about it because I didn’t want to disrespect Northern Ireland, but I just had to do what was best for me and I thought it would be best for me to switch.”

Astonishingly, in his first-ever training match with the Republic, under manager Giovanni Trapattoni, he was involved in a freak collision that lacerated his liver and emergency surgery was required to save his life as he lost a huge amount of blood.

After a speedier-than-expected recovery, Duffy was soon lining up for the Republic’s Under-19s and Under-21s and he went on to make 20 appearances for the Under-21s.

In 2012 he was called up to the senior squad to replace the injured Richard Dunne but missed out on the squad for the 2012 Euros. He had to wait until June 2014 to make his full debut and it was another two years before he was next involved.

He was called up to the side who famously beat Italy in a 2016 Euros group match to qualify for the final 16 but was then sent off as the Republic bowed out 2-1 against France. Nevertheless, under Martin O’Neill, Duffy became established in the side and in March 2018 was named his country’s Player of the Year. He told the matchday programme: “When I heard the news, I was shell-shocked, but when it sunk in it gave me time to reflect on how far I’ve come in a short space of time.

“So much has happened: the Euros, failing to reach the World Cup in the play-offs, winning promotion with Brighton, playing in the Premier League.

“The manager noticed a difference in me when he brought me back into the side two years later, and that’s because I went away, played games and I worked hard. I got myself properly fit, dedicated, and I feel like I’ve benefited from that.”

Reflecting on the experiences given to him by Hughton and O’Neill, Duffy pointed out: “Chris has given me the chance to play in the Premier League where I’m developing, and Martin has given me the chance to play on the big stages and in a big tournament.

“You take little things out of each one of them and it’s coming together a bit now, and hopefully there’s more to come. I’m still a bit raw in some things I do but I’m getting better and it’s a nice feeling to go out knowing you can compete with top players and feel comfortable.”

Duffy went on to captain the Republic for the first time in a 1-1 draw against Denmark in November 2019 and retained the captaincy in Stephen Kenny’s first game in charge, in September 2020; a 1-1 draw against Bulgaria.

As an established international, Duffy has nearly 145,000 followers on Twitter.

Looking back, by his own admission, Duffy had realised his early exposure to senior football at Everton was going to be short-lived, telling the club’s website at the time: “I know I’m not ready to play in Everton’s first team yet as I’m so young but if I’m needed I’ll do my best for the team. A loan would obviously make me better and make me more mature on the pitch.”

Initially that loan came at Burnley in the Championship, but he only played one game under Eddie Howe and, in 2011-12, he had a more fruitful loan at League One Scunthorpe United, playing 19 games under Alan Knill.

An injury to Phil Jagielka prompted Everton to recall Duffy from Scunthorpe in January 2012 and a week after playing against Hartlepool he found himself going on as a substitute for Sylvain Distin against Spurs at White Hart Lane.

Spurs had Gareth Bale, Luka Modric and Emmanuel Adebayor in their line-up but Duffy said: “I refused to get overawed by the occasion. I just treated it as another football match, another opponent, and only afterwards did I take in what had happened.”

He said: “Everton are a club that will always mean a lot to me because they gave me my chance as a professional and shaped the player I am today. David Moyes was a big influence on my career; he helped me a lot.”

Duffy spent the 2013-14 season on loan at Yeovil – “another fantastic learning curve for me” – when Gary Johnson’s side were in the Championship and although Moyes’ successor Roberto Martinez offered Duffy a new contract at Everton, he was warned he would have to wait to establish himself because he was still young and inexperienced.

So, in the summer of 2014, he decided to join Paul Lambert’s Championship side Blackburn Rovers and, while a knee injury restricted his appearances in his first season at Ewood Park, he became a permanent fixture alongside Grant Hanley in 2015-16.

When Gordon Greer’s imposing reign as Brighton centre-back and captain came to an end in 2016, Hughton turned to Duffy as his replacement (Greer went back to Rovers). The fee was undisclosed but was reported in The Mirror to be £4m.

It remains unclear where Duffy’s future lays although his performances in the opening two games of the season suggest there could yet be a future for him under Potter. The manager didn’t hold back in his praise for the big Irishman, but the defender didn’t get carried away.

Duffy opened up to the media after the win at Burnley, talking about what he’d been through over the previous 12 months, but he pointedly added: “It is only one game and a lot can still happen, but as long as I am here I’ll try and help the team whether that’s on the pitch or off the pitch with the younger lads. That is what I am here to do.”

He said he had “hit rock bottom” when affected by off-field problems (for example, his father Brian died aged 53 in May 2020), but he praised the Seagulls for continuing to offer him support and he added: “I am still taking it day by day and be like an 18-year-old try and impress every day, try and improve and try and help as much as I can. I feel like if you do that you get the reward sometimes when maybe you don’t expect it.”

Duffy also spoke openly and honestly to Sky Sports as part of the build-up to the game against Watford.
