Shane Duffy is a major doubt for Brighton’s Premier League clash with Chelsea on Tuesday night.

The Ireland defender is struggling with an ankle injury and may not be passed fit as Brighton host Thomas Tuchel's third-placed Blues.

Duffy's manager, Graham Potter, has insisted that he is very happy at one of the Premier League's "best-run clubs" amid reports linking him with the vacant Everton job.

The Toffees are searching for a new manager after sacking Rafael Benitez following just one win from 13 top-flight games.

Potter, whose contract runs until the summer of 2025, has impressed since arriving at the Amex Stadium in 2019 and has the Seagulls flying high in ninth place ahead of Tuesday's visit of Chelsea.

"I can't comment on speculation, things that are out there in the newspapers," he said.

"I'm focused on my job here, very happy here at, in my opinion, one of the best-run football clubs in the Premier League, with a fantastic owner, chairman, CEO, sports director.

"[There are] great people at the club, a nice environment to work in, an ambitious club, so I just get on with my job here and do my best."

Republic of Ireland and Norwich striker Adam Idah was on the mark against Everton

Everton sit just six points above the relegation zone following Saturday's 2-1 loss at Norwich - nine points below Brighton.

Former Ostersunds and Swansea boss Potter has been connected to a number of other clubs during his time on the south coast, including Tottenham and Newcastle

The 46-year-old also came under pressure in the job last season after Brighton failed to win any of their opening 10 top-flight home matches.

While many within the game regard him as one of most talented English managers, Potter believes his growing reputation is down to a collective effort.

Asked if he was flattered by the rumoured interest, Potter replied: "No, not really. It's just the speculation or people want to write something.

"The reality is I'm at a really good football club that helped me. I'm not here because I'm that good, it's because I'm at a good club and I have good support.

"I have people that allow me to do my job, that give me support, give me trust and these things are important, there's an organisation around the club.

"The reality of it is we're not as good as people think; we're probably not as bad as people think as well when things aren't going so well.

"You just can't help what people write or put out there."
