I think they are too one dimensional, a natural left winger who actually plays on the left wing would help, instad of the pass it to wallcott and ruuuuuuuuuuuuuuuuuuuun s***. They also need fullbacks who offer a bit more going forward as highlighted in the thread.
No doubting Wenger, he is a legend, but they never replaced pires, henry, viera, and campell...
