The first 7 words would have done tbh. He's a luxury player who's basically the cherry on the top. Would have been great in any team of Wengers first 10 years but no good in anything after that.
We were doing ok when he was playing with Santi and Alexis. If we'd had Auba up front, another DM and Leno instead of Cech, we'd have been ok with a decent back 4.
