Mauricio Pochettino says Harry Kane "has what it takes" to become one of the world's best strikers and says Spurs can match his ambitions.
The England forward netted 31 goals for Spurs last season and manager Pochettino says Kane is delighted to be starting the new season with the club he supported as a boy.
The 22-year-old has attracted the interest of a number of clubs but his Argentinian boss says: "He's excited to start the season with us.

"Any doubts about his commitment are gone. He is delighted to stay with Tottenham. He is a big supporter of the club. I think he is very happy and we are very happy he is with us.
"He is young but he is very mature. He is in a very good way to become one of the best strikers in the world. If you can do it in England and Europe, you are doing it in the best competitions in the world.
"'I think that we have very ambitious players now, the younger ones in the group, like Harry.
"We need to keep this mentality. We try to build a very strong group for the next few years to try and achieve important things."
"Harry can manage this pressure. He is young, but he is very mature. He is in a very good way to become one of the best strikers in the world."
"I think that we don't have any doubts about Harry Kane showing the same performances."
Meanwhile, Pochettino says it is highly unlikely that Hugo Lloris will be fit to face Manchester United in the opening Premier League weekend of the season.
The French goalkeeper broke his wrist in a freak accident over the summer and will only start training again this week.
He added: "His wrist was an accident. He broke it close to the swimming pool. It was unlucky because he's a keeper.
"In terms of Saturday, it's tough. It's not easy because we do a lot of work on physical condition. But maybe this week he will start to catch the ball.
"Maybe it's early to think he will play on Saturday but maybe he has a small chance. We don't decide yet."
