He is like Khedira if Khedira could shoot from distance, score bicycle kicks, dribble multiple players, throw multiple harsh slide tackles, win more than half his aerial challenges, combine in 1 touch play and send through balls with both feet.
Other than that, yes, they are the same height, nationality and similar pace.
Like I said before, he wouldn't be my first choice for CM but as a free player it's pretty hard to resist. He has one good season for us and his value goes over 40M surely at that age and pedigree.
Also, I want to see him in another system besides Klopp's. He doesn't fit the quick pressing style that well. I mean, he can do it at times but it takes a special CM to do it under Klopp.
Just a touch slower playing pace could really help him in all aspects of the game.
Bonus: It seems all Liverpool fans are giving him full marks for how he handled the contract situation. It seems that he is a "good soldier" Juve type.
