Had that turned out to be the case, the situation would have panned out differently altogether and Zouma may still win the battle in the end. Anyway, doubt Walcott did much wrong in that situation. Given that he's quick, he would have fancied himself to outrun our backline especially when we were high up the field at that point of time. Zouma did what he needed to and he did it brilliantly, showing great recovery and composure to win the ball back.
