Kane is the joint-top scorer in the Premier League this season with 17 goals as he tries to retain the Golden Boot he won last term.
Tottenham boss Pochettino revealed his star striker is leaving no stone unturned in his pursuit of that target, to the extent his manager occasionally has to give in to the 23-year-old’s fierce desire to succeed.
Pochettino said: “Sometimes he gets upset because he wants to do a finishing session in the afternoon and tell him that it’s not the right time. We say he can do it the next day.
“Harry says: ‘No, but I want to do finishing this afternoon. I want to do a double session.’ I tell him: ‘No, Harry.’ He says: ‘Oh, gaffer, come on, I feel good, I’m not tired.’
“I then tell him it’s not good for him but sometimes in the end I say: ‘OK, maybe half an hour of finishing’ – even though that means we need to call in two or three goalkeepers from the academy. That shows Harry’s determination and character.
“I want to explain that Harry has a very good character, he is very strong, very professional. He is a player who always challenges you, like Dele Alli or Hugo Lloris, and that is what I like.”
Pochettino is confident Kane will be fit for Sunday’s meeting with Everton even though he hurt his knee colliding with a post during the 4-0 win over Stoke last weekend, in which Kane scored a hat-trick.
