The Premier League’s first and second placed teams meet in next weekend’s Wembley semi-final with Tottenham in the better form.
Spurs thrashed Bournemouth 4-0 on Saturday and have now won their last seven league matches, scoring 20 goals and conceding just four during that impressive run.
Chelsea on the other hand lost to Manchester United 2-0 on Sunday and also dropped points at the beginning of the month, when they were beaten at home by Crystal Palace.
Just two weeks ago Antonio Conte’s side boasted a ten point lead at the top but in the light of United’s win that has been cut to four points, with six games left to play.
Both sides will now turn their attention to the FA Cup – with either Arsenal or Manchester City waiting in the final – and Kane has said that winning the match could also boost Tottenham’s chances of winning a first ever Premier League title.
“It could be a big thing psychologically,” Kane said.
“Of course it's a different competition so it's hard to say, but it's a big game for us, a big game for the club, a massive semi-final and you never know.
“If we win next week it might put a bit more doubt in their minds regarding the Premier League. But we can't control what Chelsea do.”
After a run of kind fixtures, Spurs have a tricky run-in which includes the last ever North London derby at White Hart Lane.
After that match Spurs will play another London derby away to West Ham, before they host Jose Mourinho’s revitalised Manchester United.
Spurs finish the season with successive away matches, first against Premier League champions Leicester City and then against Hull, who are likely to be scrapping for survival.
Tottenham have to realistically win all of their remaining fixtures if they are to beat Chelsea to the title but Kane is certain there will be some late drama.
“I think sometimes people say we're still second and Chelsea are still seven points clear - or four now - so they don't think we are doing as well as last season,” Kane said.
“But if you look at the table, 71 points with six games left is incredible. We've got to make sure we finish strongly - it isn't over yet.”
