The piece everyone misses with him (it's a thing some players have), he can be utter brick (he was poor for a stretch at the back end of last season), and somehow ends up involved in every goal, still creates chances.
Wide in an Ange system doesn't suit him, he works well in tight spaces, very physical, both anticipates and knows where others are, can pass or be the goal threat himself. With him and Solanke defenders will get bullied for 90 minutes.
The interesting piece is the we can play him and Maddison, it lifts our creativity and makes it harder for teams to nullify Maddison (we saw some of that last season).
The challenge is it puts more pressure on Bentancur/Biss behind them, although I feel Ange is adjusting slightly (FBs seem slightly less suicidal? and in certain games, seems even the wingers come back a little)
