Manchester United winger Wilfried Zaha admits the intensity of the U21 Euros stunned him.

Zaha admits he was shocked by the pressure and quality of an international tournament.

The £15million Manchester United new-boy said: "After not winning a game, we need to look at ourselves and re-evaluate our performances over the tournament.

"For me, it was my first tournament and a different environment.

"We didn't expect all that quality. I think next time we'll be well prepared for it.

"It's not that we didn't try hard enough, it's maybe we weren't used to playing in tournament games under so much pressure."
