The defender can, on his day, be one of the very best around.
Arsenal may be without Alexis Sanchez but they have Mesut Ozil who is back to a semblance of the player who left Real Madrid and a very in form Santi Cazorla who will be looking to impress again.
To keep the Arsenal attack at bay, Spurs will have to be at their best and no one will have to be better or more organised than the Belgian.
