I might be in the minority on this, but I liked Iwobi at Arsenal - my mates in a Whatsapp group raised their eyebows a bit when I declared myself "made up" that we'd signed him on deadline day, but I think he brings something we didn't already have. Carries the ball well, although like any winger he can make bad decisions on this at times, but the bit I like about him most is the passes he plays around the box. Simple, but intelligent passes which sometimes get missed and possibly aren't the pass which provides an assist, but open up chances to create goals. He did it at Arsenal and for whatever reason they didn't appreciate it. He was doing it yesterday in the first half too. He's a very clever player. His finishing was poor at Arsenal - used to seem to lose his composure when presented with a chance and I often think that was a large part of the reason the Arsenal fans were, at best, very torn on him. He faded badly in the 2nd half yesterday, but he had no preseason whatsoever so I don't think that's any kind of a concern just yet.
I actually think that he'd be better as a number 10 - Sigurdsson seems undroppable to Silva, but a little clever player like Bernard from the left interchanging with Iwobi might be really exciting
