It was the first year the Welshman spent in Swansea’s first team.

And footage has now emerged of the youngster showing off his shooting skills.

The Welshman is out in Dubai running some control and passing drills.
But then United’s new boy is given a shooting exercise.
James is given a ball by one of the coaches and he has to control it before shooting on goal.

James hits the target with four out of the five shots, volleying three of them first time.
This footage was shared on Twitter over the weekend before being published on Reddit.
