The left foot thing is right and was frustrating when he didn't pull the trigger, but he was the only one looking for the ball at a lot of points in the game today so the "getting involved" point is harsh.
Bit harsh on Agustein, I personally feel he was one of our best players before going off. He was constantly looking for the ball. He made some very good chances, including starting the move which resulted in out goal.
To me, he looks quality already and just needs a run in the team to push on...
