He's Khedira on steroids. Never should be a B2B option but good as a holding mid.
Like when Khedira is sitting in front of the defence and sees an opponent he would think, "Damn I wish I was strong enough to make a tackle here." But that's what Can does.
Or when the ball actually comes to him with room to run a bit, "Damn I wish I could sprint just enough to get up the field to Ronaldo". But Can can do it.
Or, "Hmm... I have the ball here in the final 3rd with everyone in front of me. It would be cool to play a 1-2 with Dybala to get in a scoring position."
