Great, Crystal Palace are bad enough as our bogey team, giving them Benteke is a confirmation of our annual 6 point donation to Palace...
Look at it like this - we lose to Palace anyway so why not sell them Benteke for a very decent price (essentially making him a "swap" for Mané)?
I feel like Benteke would prosper at Palace and recreate his Villa form there. He was never gonna work here so I don't mind if he does well elsewhere tbh
