I'm not going to cunt you off because frankly I can't be bothered, me old mucker.
But everything you just said was, imo, wrong.
We don't need that pace for balance - Kulu's positioning and reading of the game, plus his physical strength are his key attributes. He doesn't need that pace.
I agree we have to have pace somewhere, obviously, and that's where a) Son comes in, and b) what we need to be looking for from our wingbacks.
Blasting Kulu for being slow is like blasting Dier for his goalscoring prowess. That's not what he's in the team for, and that's not his thing!
