There are a million things he could have done but having a shot is the very least. He could have took it first time with his left, attacked it and went with his right. He could have even took it across his body and took it on his right. Even when he drags it back he doesn't take the opportunity to hit it goal-ward. It was AWFUL.
The ball was coming at pace, it was either control it with the left or put a left for swinger on it... The other options weren't available. After the touch his shot would probably be blocked by Martinelli, and after the drag back his shot would almost certainly be saved.
