Sunderland boss Steve Bruce says it would take a 'wonder bid' for the club to part company with £13m striker Asamoah Gyan this summer.
The 25-year-old has been linked with a move away from Wearside, with Tottenham Hotspur and Zenit St Peterburgh among the clubs reportedly interested.
"I haven't had a telephone conversation with any agent, no offer from any club," Bruce told BBC Newcastle.
"He's going nowhere unless we get a wonder bid that comes out of nowhere."
Bruce added: "As far as I'm concerned I'm looking forward to seeing Gyan being ready for the Premier League better than what he was last year.
"I think he'll be better, he knows what to expect and I'm expecting big things from him."
Ghana international Gyan scored 11 goals in 33 games for Sunderland, following his £13m move from French club Rennes in August 2010.
Bruce's attacking options at the Stadium of Light have been bolstered this summer by the arrival of South Korea striker Ji Dong-Won, and England Under-21 forward Connor Wickham to complement Gyan, Fraizer Campbell and Stephane Sessegnon.
"Sessegnon showed toward the back end of the season, for me his best position is in and off the front - he got three goals in four games at the end and we started to see his best position," Bruce added.
"So that was in my mind when we decided how to complement the team with him and Gyan.
"In the Korean boy [Dong-Won] and Connor Wickham they're both physically big, they will lead the line.
"They're young, and haven't played at this level before which is always a risk, but for the future of the club I'm convinced that they're two very good young players."
