The Arsenal

To me world class is top 2-5ish players in your position in the world, it requires consistency of top performance, and there is also a base standard you have to clear (this is what determines whether their are 2 world class players at a position or 5).

I would say Saliba, Saka, and Rice are world class. Odegaard was playing at a world class level last season and certainly can be world class, but doesn't have the consistency yet.

I'd also shout out Martinelli who think can and will become world class, but isn't yet.
