Seriously though - I'd accept Evans as a short-term solution if Wenger is hellbent on signing him, but make no mistake: he's just going to be another Squillaci or Debuchy for us. He has no use beyond this season. He's not a starting player unless we're aiming for another season in Europa League, and the second he realises that he will tail off and become a burden. He's 30. His last big move will be all about picking up a paycheck and maybe the odd cup to improve his CV.
Everything about him screams bad signing with this in mind.
