He isn't going to leave Leicester to sit on the bench now they have just been promoted.
Plenty of better GK's than him.
If we are looking for back-up keepers then Speroni is a good bet on a free transfer. He's going to turn 35 so would probably be content with being our cup keeper. Could probably give him CL, CC and FA cup. Wouldn't demand high wages either coming from Palace.
Marshall could be an option with Cardiff going down.
Or Ruddy could probably come for a few mill with Norwich likely to drop. Would really challenge Chez for the GK spot and is English so wouldn't use up a spot for foreign players.
