He does have a great eye for a pass, and is very creative as well as being a good finisher. It's why I think Wenger has refrained from playing him as the main striker, because it kind of takes things away from the rest of his game.
Don't get me wrong, he tends to hold on to the ball way too long at times, and he can lose possession a lot....sometimes in dangerous situations. Sometimes it's a case of why doing a straight forward pass from A to B, when he can do a dribble, 3 pirouettes and lose and regain possession to get there.
But the good thing about him is that even in games he is playing average, he's always capable of providing a game changing moment.
