Mauricio Pochettino insists no money in the world can take Harry Kane away from Tottenham.
Kane scored twice in Spurs' victory over Norwich on Saturday to take his personal tally to 11 Barclays Premier League goals this season and 27 in 2015, which broke Teddy Sheringham's club record for a calendar year.
The 22-year-old has reportedly attracted interest from big-spenders Manchester United in the past, but Pochettino is adamant Kane will not be leaving White Hart Lane regardless of the bid.
"There is no price. No-one can buy him," Pochettino said.
"He is not for sale. There is not a value because it is impossible to put a price."
Kane's remarkable 12 months has included two hat-tricks, six doubles and 32 goals in all for club and country, including one 79 seconds into his senior England debut.
The striker went eight games without a goal for Tottenham at the start of the season but any 'one-season wonder' jibes have since been quashed, with Pochettino's men now sitting fourth ahead of Monday's visit to in-form Watford.
Kane may feel added motivation, having been invited for trials with the Hornets as a youngster before Spurs stepped in and made the definitive offer.
"I was there for a four to six-week trial and then before it went up I went to Spurs," Kane said.
"I was very young at that stage. I've played there on loan for a couple of clubs.
"They've been doing well. They got another good result at Chelsea (2-2 draw) on Saturday so they're going to be full of confidence as well.
"You can't take any game for granted, like 'this is a game we're going to win'.
"Everyone is beating everyone and teams who you thought were going to be down the bottom are up near the top. We have to be focused like we were on Saturday against Norwich."
Spurs are in good form, having registered back-to-back wins since their shock defeat at home to Newcastle two weeks ago.
That loss took their number of points lost from winning positions to 11 this season and Pochettino was noticeably animated when his side led Norwich 2-0, geeing up the crowd and hounding his players to go for a third goal.
"Sometimes I think it is good when you feel from the touchline the energy is a little bit down, always I can help the players, the people, and you know in the Premier League the game is not finished until the referee blows the final whistle," Pochettino said.
"We needed to kill the game and always you need your supporters to support you. There was a moment after 50 minutes in the second half we play brilliant but did not kill the game.
"There was a moment when we missed a pass and only you hear the silence and I start to shout and try to help the team to give them more energy to kill the game."
Tottenham midfielder Mousa Dembele is struggling to be fit for the match at Vicarage Road after picking up an ankle knock against the Canaries.
