AWB doesn't make overlapping runs, he doesn't cross into the box, he runs out of ideas in the final 3rd, and passes the ball backwards. I watch him from my seat at Old Trafford every week. Defensively, he is often out of position, cannot hold a line with the back 4, cannot defend the back post for corners or crosses.
You only have to watch Coventry's 4 goals at Wembley. AWB was involved in all of them. Lost his man for the first cross. Turned his back and deflected the ball into his own net, gave a penalty away, and for the forth, he was a toenail away from playing them onside. All the other defenders were playing a higher line.
