See I wouldn't call Matic for example a powerhouse. I think you need to be really quick as well as strong to be that. It just so happens that more black players than white players are powerful IMO
Cronaldo is really powerful but obviously has more to his game. Sissoko is probably the player that is most easily described as powerful as he isn't that good at anything else
Aye, I'm much more excited by his tackling and intercepting than I am about his passing. He's a very comfortable passer rather than a ball through the eye of the needle type
