What a load of tosh. Chelsea will bid for him even though they can't sign anyone which will suit Palace because they want to sign a Chelsea player and then they will keep Zaha for a season
So basically that means no bid by Chelsea, Zaha has to play at the same level for another season to ensure Chelsea are interested next season and then they all negotiate again but he will be a year into his contract so a chance his value goes down and Palace miss out on a bumper fee this summer.
