Spurs have had a difficult transfer window.

They're yet to make a signing and were thrown into turmoil earlier this week after Danny Rose admitted he wanted to leave.

Mauricio Pochettino has already lost one of last season's first-team stars this summer.

Kyle Walker joined Manchester City in a deal worth around £52m last month.

And Crespo, who made 49 appearances for the Blues, has urged Kane to follow Walker out of north London.

“Harry Kane is a great striker but he's just like Tottenham," Crespo told The Express.

“You need to win. If you win you are a great striker, you need to win. He's demonstrated he's very important.

“It's like Alan Shearer - a big striker but with Blackburn, bang, he won. After that, boom, national team, big. If you win, you're another level.

“Kane needs to help the team win trophies and to do it with Tottenham would be great.

“He tried to do it last year and didn’t. If it doesn't happen, Harry Kane must change. He must.

“He must move to win, to a big team, to Chelsea, although Chelsea would be difficult.

“Maybe Manchester City, why not? Manchester United after signing Romelu Lukaku would be difficult.

“Next season, everything could change with Kane.”
