Pretty good tbh. He often played out wide in a 4-3-3 with Hoffenheim, can dribble reasonably well, strike the ball competently with either foot.
It's worth noting that even though he seemingly appears like a bit of a journeyman crock with this whole West Ham saga, he was a very highly rated striker a few seasons ago. I remember him being linked to the likes of Juve, Arsenal etc.
Cheers mate! Sounds good!
