Manager knows best.I don't know what he got upto at QPR, anyway, the point remains that 110 minutes is no way enough to decide if he can be useful, especially when you see Smalling playing so many games (badly) at RB.
Do you remember when Zaha was given very few chances even when Valencia did jack shit?
Everyone went up in arms and complained on why Zaha was not playing. This happened with every game Valencia played badly. Then one game we played badly and Zaha came on for the last 10 mins and everyone was excited and relieved. Guess what? He played shitter than Valencia which is quite and achievement: he did not track back, he fumbled every cross over etc.
Suddenly, everyone went quiet and did not want to show that how wrong they are. You may say well he did not get the chances like Fabio and that caused him to not play well. Ok, what happened when he got loaned to Cardiff city? He didn't perform and didn't track back.
He was still Raw. Again, the manager knows best. You may say well Moyes doesn't know anything and he is wrong, well Fergie couldn't of been wrong too? He didn't play him that much in the last 2 years of his time at united.
