Harry Kane will cost a premium for any club wanting to prise him away from Tottenham, according to former Spurs boss Harry Redknapp.

England captain Kane is reportedly keen to end a career-long association with the north London club in order to pursue major honours.

Manchester City, Manchester United and Chelsea have all been linked to the 27-year-old, along with Paris Saint-Germain and his ex-manager Mauricio Pochettino.

However, Redknapp knows first half what a tough negotiator Tottenham chairman Daniel Levy is and he expects his old boss to extract top dollar.

"It will not be easy. You are dealing with Daniel Levy and he's not easy to deal with," Redknapp told talkSPORT.

"He is not going to go, 'Okay, Harry, I understand, off you go mate, we will sell you for cheap'.

"He is going to cost a king's ransom, believe you me."

Redknapp expressed surprise at Kane apparently agitating for a move, given his exulted status at Spurs.

"I thought he would stay," he said. "His life is fantastic, he is the leader of the club, his family is here.

"But I suppose he has got to the stage now where he has won all the individual accolades and now wants to get some trophies on the board."

As such, Redknapp feels the Tottenham faithful should be understanding towards their talisman, who he thinks would be a transformative singing if he ends up at Old Trafford.

"If they are sensible, they [the fans] will look at and think he deserves the opportunity to go and win a few trophies," he said.

"I would be surprised if he went to Chelsea. If the fans have any sense, they would understand his situation.

"If you want a guarantee to win trophies you go to Man City or Liverpool, but he could turn Man United into title winners. He is that good.

"With his goals and everything he brings, they would be very close. Whoever gets him, he will improve them massively. He will be a great signing for somebody."

Redknapp added: "He is a great lad, a great professional and an absolute gent to work with. He would be amazing to have at your football club."
