The first miss was especially pathetic. He just has to set it out a little wider with so much of that side of the goal to aim at, and then lift it so the outstretched leg cannot save it. It's an easy finish for a professional player in the Premier League. The one with Walker is closed down well by keeper and he has less of the goal to aim at. He had another one too but I can't remember it well.
If he could cross and finish consistently he'd be one of the best attackers in the world. His pace is devastating.
