His play is similar to Nasri's. He does not have particularily good vision (yet), but he can dribble, has good technique and just overall seems like the kind of play Wenger likes. A good technician, with the potential of becoming possibly very good, and with a minor reputation in football so he won't be expensive.
He only has 3 assists this season (but 7 goals), and his low tally given his position is largely because the source of most of Montpellier's attacks are crosses from the wings.
I like him, but I don't think he's much better than Ramsey. Possibly more responsable with the ball though - he doesn't lose it nearly as much. Hazard is definitely better but probably not 10 times better, despite probably being sold for that.
Of course, this could all be an invention by the journalists.
