No problem with his work ethic mate. He does generally put in a shift. He just doesn't have the physique to press like Gana or Schneids. He has a languid style that reminds me of Le Tissier, but he isn't lazy. Unsy's had the under 23s playing a pressing game long before Koeman joined the club.
He sometimes switches off at times which is something he needs to sort out. My biggest issue when I've seen him is that he drifts out of games for periods. But he's absolute quality on the ball and is very capable of scoring goals like he did today. He can pick a pass too and is also excellent from set pieces.
I'm delighted for him that he's had an excellent start to pre-season. I just hope he doesn't get over hyped as he won't play like that every time he takes to the field. But I'd like to see us keep hold of him, at least up until January, and see how he does in Europe and some cup games. Maybe come off the bench in some premier games against teams who park the bus.
