West Ham United legend Tony Cottee believes the dressing room will be concerned over the club's plans this summer.
Cottee is worried by what is happening with the players under new owners David Gold and David Sullivan.
He told the Daily Star Sunday: "Who (Avram) Grant keeps and who goes worries me.
"The club claim virtually every player is up for sale but that should not be the case.
"They need to keep their best players, not let them go. Talking to fans, I see half are undecided by his appointment and the rest see it as a good move.
"Me? I don't know. I am not sure. I wish him well but, for me personally, the jury is out. As I said, I am really, really concerned."
