Every one of Kane's goals this season could have been scored by any decent forward in the PL. There is nothing special about those goals at all. Swap Richarlison for Kane and he scores every one of those 7 goals. And you could argue that every player on our forward line and MF (including PEH) has pulled off excellent passes this season.He's the 2nd top scorer in the entire league & regular pulls off excellent passes for us. He executes it.
Kulu on the other hand, does things no one else on the team can. The only thing he can't do is score the types of worldies Son does and maybe execute long passes like Kane otherwise he does everything well or even better than those two (this season).
