It's quite short sighted to suggest Theo is some incompetent footballer that needs to be sold.
Consider that we need homegrown players and consider that our club prides itself on development etc etc.
He has flaws, but he has strengths. So do virtually all players. The hipsters will look at anyone that isn't iniesta and get all high and mighty, but in reality Walcott was a proper big game player at one point, and has shown that he has a place at Arsenal.
