At Shakhtar, he was the tempo setter in a 4231 next to an anchor man. As well as being the dictator, he had the dynamism to press well and win possession back.
It seems that he likes to get on the ball, and wants to be the player to start our attacks, but he is very rash with his passing. Can't fault his effort and mentality because he doesn't hide, but he's not quite the passing midfielder we needed.
I wouldn't get rid next season because I think instead of using him as a deeplying playmaker, we should use him as a ball winner. Like I said, although his passing is rash, he presses well and wins the ball back quite often.
Obviously, this means we then need to have a deeplying playmaker next to him - someone who can set the tempo. Pjanic, Kroos, Verratti, Rakitic, etc.
Not sure I would start him next season, and I think we need a minimum of two midfielders with Herrera possibly leaving, but he could remain a squad player and like Lindelof, we can only hope that he settles well next season.
