The deflection was unlucky, really unlucky. However, playing Walcott onside wasnt unlucky, it was just bad defending in the first place. I think Rojo did this earlier in the game, the only difference is Rojo played on Ramsey and then carried on and cleared. Rojo played on Walcott and it lead to a goal through a deflection (OG tbh).
Im not going to rate him on this game. I say it again, its not his fault. How many games has he played for us as LB? Not youth, I mean first team? Since the Leicester game, it seems he always has a mistake in him. That Leicester game where he got sent off was the worst thing that could have happened to him.
I do think he needs a loan spell away from the club next season and to be playing every game (and in one position).
