Fulham manager Chris Coleman says he has no intention of selling match-winner Steed Malbranque during the summer transfer window.
Malbranque, who rejected a move to Manchester City a year ago, scored the last minute goal which gave Fulham a 2-1 victory over Stuart Pearce's side - their first away win of the season.
Coleman believes the Frenchman could walk into any other team in The Premiership, but is hopeful of persuading him to sign a new deal at Craven Cottage.
"If I am talking about building a top squad, there is no point us selling our best players and Steed is one of them," said Coleman, who added Wigan's Jimmy Bullard to his squad on Friday.
"We are desperate for him to stay and want to extend his contract immediately.
"We can play Steed centrally, we can play him wide right or we can play him behind the strikers. And his finish today was top quality."
After losing the likes of Louis Saha and Edwin van der Sar over the last couple of seasons, Coleman is determined he will only let more big names leave if Fulham receive bids which cannot feasibly be turned down.
"Let's be honest, we are looking at Malbranque, Boa Morte and Diop," he said.
"They would get into most Premiership teams and quite a lot abroad too. That is just a fact.
"But what do we want to do. We could cash in and make a lot of money - and if we did that I would make sure we got more money than their actual value - or we
can try to retain them.
"You have to draw the line somewhere. You can't keep losing your best players and those three are our best players.
"If we were going to lose them, it would have to be for a staggering amount of money. But what is the point just going round in circles."
