Haha nicely put mac but think of the reason why we decided to but him in DM? Because yes he played the CB position well BUT, when he often decided to do one of his hopeful runs with the ball up the pitch, which don't get me wrong has a fantastic style of play when he does so,but sometimes he does f**k it up (primary example vs Leeds) where he then is unable to catch up with the interceptor of the ball and leave a big gap in our defence 4 the other team to score.
Ultimately, what he needs to do is learn where his place is in the team and as his maturity grows in the way he plays, then so will his decisions.
