Sherwood was speaking at his pre-match press conference ahead of the weekend’s visit of Sigurdsson’s Swansea, just a few hours after the in-form Kane had received first senior England call-up.
The striker’s stellar breakout might have come this season, but it was the Villa gaffer who gave him his first Premier League start against Sunderland last April – a match in which he opened his top-flight account.
While Sherwood would leave White Hart Lane at the end of the campaign, the former trainee has since gone on to establish himself as one of Europe’s hottest front men, netting 26 goals in 42 total appearances this term.
Nevertheless, his old boss has been quick to stress that teammate Eriksen and the since-departed Sigurdsson were crucial figures in helping Kane reach his current heights, having mentored him for hours on end on the training pitch.
“I think a lot of credit should go to Christian Eriksen and Gylfi Sigurdsson,” he said. “As much as Harry was a fantastic trainer, those two guys, along with Harry, spent hours on that training field striking balls, working on their left side, working on their right side.
“I think they showed Harry how to train properly. They have to take a lot of credit.”
Sherwood also revealed how Tottenham officials were willing to sell Kane last winter in order to bring in other attacking reinforcements, but the man who gave him his chance was adamant that he would not be shipped out.
“When I first put Harry in the team, Roberto Soldado was on the bench,” he added. “After 30 minutes, if Harry hadn’t scored they’d have been signing for Soldado to come on, so he took his time to win over the fans.
“It’s just great that I resisted the temptation to get rid of him last January because perhaps he wouldn’t be the star he is for Tottenham now.
“It was never close in my opinion but there were people who wanted to bring in another striker and sacrifice Harry Kane. I wouldn’t allow that to happen.
“He got his opportunity and now he’s bouncing forward.”
