Roberto Martinez is confident Wigan can hang on to the services of their key men this summer.
Speculation continues to suggest that the likes of Charles N'Zogbia, James McCarthy and Hugo Rodallega could be lured away from the Latics.
French winger N'Zogbia came close to joining Birmingham last year and he now has just 12 months remaining on his current contract.
McCarthy and Rodallega have enhanced their reputations during their time at the DW Stadium and reports suggest all three men are drawing admiring glances from afar.
Martinez, though, insists he is under no pressure to part with any of his players and is confident he will have a full-strength squad from which to select in the 2011/12 campaign.
"There is no reason to think otherwise. The players are under contract," said the Spaniard.
"We've got a lot of good players and it is understandable people are looking at them.
"There's been a lot of media speculation - that is part of being in the transfer window - but I am more focused on trying to reach the targets we set, get as fit as we can and enjoy every player we have in the squad.
"We are working hard in pre-season to continue our development.
"We don't know what is going to be around the corner so we are going to enjoy having these players but as a football club you have to be prepared.
"Every player comes back to the club where they work for pre-season so they are not in the press or reading papers about themselves.
"They know they have to work hard to ensure we start the season in the manner we finished it. Don't think players come back thinking 'Where am I going to be?'"
Martinez has added former loan star Ali Al Habsi to his ranks during the transfer window and claims he is only looking to carry out one more piece of business.
"I feel we are probably looking at another player," he said.
"We have lost Tom Cleverley, who went back to Manchester United after doing very well, but everyone else is stronger after another year's experience.
"Tom staying was not an option. He came to us to get Premier League experience to help his development and he will go back to Manchester United and really fight for his place."
