Matthew Upson admits he would be 'really frustrated' if West Ham United sold key players in January.
Rumours suggest the Hammers could look to cash-in on a number of their high-profile squad members in order to ease fears over their reported financial situation.
Icelandic owner Bjorgolfur Gudmundsson has been affected by the current economic climate, and it is claimed manager Gianfranco Zola will have limited funds in the New Year.
But Upson, who signed for West Ham from Birmingham in 2007, is hopeful Zola will keep the squad together as they look to build on their current position of 13th in the Premier League.
"In the current climate there haven't been any assurances and I would not expect any but if I am to stay at West Ham and we sell key players in January, then that would really frustrate me," he said in the Evening Standard.
"I signed for the club because of the vision they had and if players went now, that would really disappoint me."
Goalkeeper Robert Green added: "It is not down to us what happens in the future but from the players' point of view, every time we go out there, we are all showing we want to play for the club and we want to do well.
"Within the training ground it is a happy camp and a hard-working one which hopefully can only get better."
