Tottenham boss Mauricio Pochettino admits Harry Kane has struggled since making his England debut last month.

Pochettino believes Kane and Ryan Mason have not been able to show the same level of consistency since they returned from England duty and hopes to see a big improvement when Spurs face Newcastle.

The manager said: "When players get their first call-up, they try to show they are good enough and try to impress the national manager, and because they are over-motivated they expend a lot of energy.

"When you come back to the team, the consequence is that for two or three weeks you are a little bit down. It is normal and this happened at Southampton too.

"I remember my first call-up for Argentina against Holland. I was up on a cloud for a month after it because it was unbelievable to play for the national team. When I got back to Espanyol it was difficult. I'd been away for 15 days with my national team and I came back and I said, 'Oh, but now I play with Redondo, Batistuta...'

"You feel like a superstar and then you have to go back to Espanyol."
