I think Perez needs to move on for his own good.Meh. I wouldn't take him over Giroud or Perez. Personally think it's only worth bringing in another forwards if they are TOP class.
Even though when he played earlier in the season he showed he can score goals, for some strange reason Wenger won't play him nowadays and in fact he hardly ever gets on the bench.
He has never been given a proper chance with us and its something I can never understand considering his ability.
