Welbeck - Injury prone and shit
Deeney - Fat and very shit
Zaha - Would cost 40+ million not shit though
CP would never sell Zaha either, he's literally the only way they're likely to stay up.
Welbeck is too injury prone for us to take that gamble. Don't think he's shit, but his finishing is hit or miss. The far bigger issue is that we can't pin our hopes on a striker that could very easily be missing huge chunks of time.
