Odd signing in the 1st place, out of all the quality at Southampton we went for the unknown one that didn't shine, not a real surprise he's not been good enough, always the cheap option with Wenger, made the same mistake when he signed Walcott when he should have signed Bale too.
Sell him, not good enough.
Why do we always do this, sign middle of the road players we end up being lumbered with for years, Chambers, Giroud, Walcott, Welbeck, Gabriel..... so much money wasted!
