We've seen this before though right, players with no end product.....he's decent and energetic but in the final third he's been hopeless thus far, his shooting is weak, he picks the wrong option too often and just doesn't deliver.....bit like Eboue did.
I'm not expecting many goals from Gervinho though to be fair as he had a very average career goal record in France as well.
I think he has something to offer, but I don't see his end product improving under Wenger who's teams in the last 6 years have often had players who lack that end product.
