Stuart Pearce is frustrated two of his key players, Joey Barton and Sylvain Distin, have not yet committed their futures to Manchester City.
The pair have been offered fresh terms to stay at Eastlands, but as yet neither have put pen-to-paper and extended their stay at the club.
Barton caused uproar earlier in the campaign after submitting a transfer request while Distin has just over one-year remaining on his existing contract.
"We've made him an improved offer, but we still seem to be at a sticking point," said Pearce.
"And I don't think Sylvain wants to leave. If I was in Sylvain's situation or Joey's situation I'd stay."
Pearce is happy his players are ambitious and want to win silverware, but he does not see why they cannot fulfil their desires at the City of Manchester Stadium outfit.
"Players talk about ambition and it's a great thing to trot out," he added. "But they should go out and win more games, then we'll all satisfy our ambitions together as a group.
"Ambition should not be a problem. Ambition comes from the 11 players who start a match. They are the ones who can dictate how far this club goes."
