He's great. He played 83 games for my Dortmund team, scored 22 goals and made 17 assists. He's warming the bench right now because I have great regen for his position but, even after 4 years, he is still a player who can play at his best.
Personally I have not had any luck with him. Tried him in my poacher role (where Lewy and Barrios bang them in for fun.) and all he did was miss sitters, something that I did not expect from someone with 17 finishing. In my AMC and AML roles all he did was waste build-up I found taking shots from weird angles or making terrible passes. His stats are great, he is young and I want him to succeed but at least in my experience he has been one of my worst players.
