actually he is considered as a great talent , haven't seen him play so can't say for sure , probably some of the members who whatch EPL can give more info about him
He is Wales youngest ever player at 16 iirc, and their first chioce.
Also, he hasnt played that much for Tottenham because he has had a serious injury for most of the season. He was close to joining Man Utd but Spurs were willing to pay the £10m Soton wanted.
He is left back and left wing, has a good left foot, good at crossing, great stamina, and a free kick expert. Need to improve defensively but thats obvious because he is only 18.
