British media teamtalk reported that in the pre-match press conference against Crystal Palace at Tottenham Hotspur, Conte confessed that he was also scared to let Kane start every game. After Conte took office, Kane played almost every game for the full 90 minutes, including the European Cup.

Asked if he was afraid that Kane would still play the full 90 minutes on such a busy Christmas schedule, Conte said he was also ambivalent: "Yes, of course I know that. I'm well aware of the risks of getting Kane to start and play the full 90 minutes, but without Kane, it would be difficult to play from the first minute, he's an absolute core pillar of our team. ”
"I've definitely talked to him these days, and I've been talking to the players directly because I want to know exactly what the players are doing. If a player feels tired, then we have to have a clear picture of the situation. This is very important because through communication we have to manage this time precisely. You know, this Christmas schedule is not easy, not only for Tottenham, but also for other teams in the Premier League. Conte said.
At present, Tottenham have only one center in the Squad, Kane, and none of them are substitutes. Previously, Nuno had taken the approach of bringing the 17-year-old Scallet to the centre forward position to play in the European Cup, but Scallet was also just a winger, Mourinho had said that Scarlett had the potential to become the next Rashford, but at the current age he could only play on the wing. The most helpless thing is that Scarlett also suffered an injury some time ago, and conte currently has only one center in his hand, Kane.
In previous seasons, Kane had suffered six serious injuries to his ankle. Because of this, Kane's current speed of play is significantly different from his peak. In the summer transfer window, Kane was bent on moving to Manchester City, but was blocked by Tottenham chairman Levy and ultimately failed to do so.
