I think Walcot improves us his quality is without question and we badly need pace and support players for the front position he would radically improve our cutting edge and i think protect our flanks, we wont have teams double teaming our full backs and leaving Walcott spare.
Im not a fan of the mentality at Arsenal it seems very snow flake to me and that is my one concern, Walcott has always struck me as someone who may surrender ambition to contentment. Maybe i am wrong but thats my impression.
On signing alternatives Malcom etc. I think you have to recognise the cycle we are in. When you look at City and Chelsea and how they developed they had to sign the best of the rest in their innitial stages of development before they moved on to the Hazards or Agueros. They were initially making signings like Joe Cole, Duff, Santa Cruz, Adebeyor etc. Its a phase of development you have to succeed at and it often comes with blowing to much money on the best of the rest to get you were you need to be. We need to be in for players like Walcott.
