He used to be so quick too and so strong. I think he has lost his pace and his legs. That is probably why he does not want to move upfield and get caught as he would not be able to come back to defend. It is not only yesterday but any time he has played with Mata. Maybe he knows that the two opposing players are going to double up on him as there will be no cover from Mata. These things cannot be taken in isolation. Yes he is past it and we need a new RB but so far Dalot has been founded out when defending. I feel up to now Dalot has been the poorest of the right backs so far.
