He doesn't trust the other players, and I don't blame him.
Obviously he's lost some physicality, but years ago he'd run forward because he could trust Pienaar to make an option, hold on to the ball and give him it back. Plus he always knew that, if he did get caught out, Pienaar would track back or Lescott, Distin, Jagielka etc. would sort it.
Now he looks up and sees no one in front of him so has to hit a ball inside to one of our dreadful number 10s, and hope after he's lost it that Ashley Williams can save the day.
I don't think any left back in the world would look particularly great playing for us at the moment.
