Tottenham midfielder Ryan Mason says his England call did rattle him.

Mason admits suffering sleepless nights during the period this season.

"The first time, emotionally and everything it took a lot of out of me," said Mason.

"I think gaffer said it as well, for two or three games I struggled physically and I didn't realise how much being called up took out of me. Why? Just the emotions of it. Obviously making your England debut is your proudest moment as a player and I don't think I slept that week.

"It was just due to speaking with people and the excitement of what had happened. Obviously that ended up having an effect on me on the football pitch. But the gaffer stuck with me and I think I have learnt from that. Now, hopefully, when I am in that position again it won't affect me like that again.

"In the last two or three games I felt back to my old self and there is no sense of wanting to rest. I am excited and I want to go to play for my country again."
