Co-owner David Sullivan will listen to offers for every member of the West Ham United squad this summer, apart from midfielder Scott Parker.
Parker's winning goal in Saturday's 3-2 victory over Wigan Athletic finally ended the relegation concerns which have dogged the Hammers during the second half of the season.
However, Sullivan has been less than impressed with the rest of the squad at the 17th-placed club since he and David Gold took a controlling stake at Upton Park back in January.
That means the likes of England trio Robert Green, Matthew Upson and Carlton Cole are all available for transfer this summer.
Meanwhile, it casts fresh doubts over the future of manager Gianfranco Zola beyond the end of the season.
"If we get the right bid we will sell any player, apart from Parker," he told The Sun.
"That is the case with most teams other than Manchester United. But we have to improve the side.
"Finishing where we have done is anything but satisfactory."
