CountryRoyal No he’s not an average player but nor is he world class, there is stuff in between. As others have said world class should be reserved for the best of the best, your Messis, Ronaldos, etc.
Zaha is a very good player, nothing more nothing less.
The underlying point that he's clearly way better than we can expect to face regularly in the championship is inarguable.
Anything else is just pointless semantics about what word to use to describe his level of quality compared to other players way better than we'll face. Who cares.
