Marouane Fellaini has stressed his desire to stay and fight for his place at Manchester United.
Sunderland have been linked with a host of Man United fringe players - including Fellaini - ever since David Moyes took charge at the Stadium of Light.
Moyes confirmed Adnan Januzaj and Fellaini both interest him but he admitted he doubted whether Sunderland would have the financial clout to sign Fellaini.
The Belgian international has now come out and stated his desire to stay and fight for his place at Old Trafford, despite the impending arrival of Paul Pogba for a world-record fee.
"When you play for United you have to have competition," the 6ft 4ins midfielder told MUTV.
"Everyone has to fight for his place; I think that’s why you give everything on the pitch.
"It’s not easy, so if you’re not good or you don’t do well, the other players then take your place and I think they always push you to be the best.
"I think I can help the team, I can contribute, I can do well for this team.
"I think the manager trusts me. He knows what I can do, he knows my qualities and that is important.
"I want to give everything for the team," added Fellaini, who was signed by Moyes.
Sunderland have also been linked with a move for Man United and Northern Ireland defender Paddy McNair in recent days.
Moyes has admitted there would be fringe players at both of his previous Premier League clubs that would interest him.
Speaking last week, Moyes told the Echo: "There would be players at both clubs that would interest me if they were available.
"But what we must not do is get people’s hopes up because that might not necessarily happen.
"A lot of clubs will be going to those two clubs asking if their fringe players are available.
"We do have to get players for the team and also for the squad who we think have got a good chance of progressing in the future and becoming good players."
Meanwhile, Sunderland have appointed Mick Doherty as their new chief scout and he played a role in the £8million move for new centre-back Papy Djilobodji from Chelsea.
Doherty - who previously worked with Moyes at Everton - left his post as Chelsea's international senior scout last month and is reported to have left on good terms.
Doherty, who helped discover Seamus Coleman at Everton, was in the stands at Ewood Park on Saturday as Norwich beat Blackburn 4-1.
