Martin O'Neill is confident Sunderland can fend off reported interest in the likes of James McClean and Stephane Sessegnon.
Both men have been standout performers for the Black Cats this season, with McClean having burst onto the Premier League scene and Sessegnon having showcased his undoubted ability.
Speculation has suggested that big-money bids could be tabled for the pair this summer, with Manchester United said to be tracking McClean while Arsenal and Paris St Germain are keen on Sessegnon.
Sunderland boss O'Neill claims to have paid little attention to the rumours, with it his intention to build a competitive squad, not destroy one.
He has only recently tied McClean down on a new three-year contract and Sessegnon still has two years left to run on the deal he penned upon his arrival at the Stadium of Light in January 2011.
O'Neill told The Shields Gazette: "I haven't any cause to be overly concerned, primarily because I haven't given it any thought.
"But these are the type of players we need to keep at the football club.
"If we are going to progress, these are the players the fans want to see, the likes of McClean and Sessegnon who both belong to us.
"We've just given a new contract to James who is worth every single penny out of it, there's no question about that. His attitude has not changed one drop.
"If I was advising him, his immediate future has to be at our football club. He's going to play pretty often at the moment.
"I would love to be able to say to him that his place is in jeopardy. But he holds that place on merit at the moment, and he's still just learning the game.
"Sessegnon is a bit older, and I think he has improved.
"He's a very accomplished player in a lot of positions, but we've given him a position where he can work wonders for us.
"He's enjoying his football, and we'll do everything we can to keep him at the club.
"I think he is happy in the way he's playing, but he's obviously going to attract attention from major football clubs in the European scene."
