Coquelin puts his head where it hurts and as a Premier League team, with an already soft style, it's a more important attribute than people give credit. He broke his nose like times in a row last season doing just that. That kind of mentality seeps into the rest of the team and sets a tone. We've already got the Ozils, Girouds and Walcotts to send us the other way, we don't need any more of it.
Kante would probably come in and progressively shy away from 50/50s as he adapts to Wenger's management.
