The two sides meet in the FA Cup semi-final at Wembley next weekend and Kane warmed up with a goal for Spurs in their 4-0 demolition of Bournemouth on Saturday.
The strike made him the first Spurs player since Jimmy Greaves to score 20 goals in three consecutive seasons.
Kane said: “We’re feeling as good as we’ve ever done, Mentally we are strong, and we’re feeling ruthless at the minute. So once we go ahead we look to kill the game off.
“It’s always nice to find out you’ve broken a record. Jimmy Greaves was unbelievable. A club legend. He scored goals week in, week out.
“It’s important for me as a striker to be consistent, so to reach that 20 goal mark again is great.”
Tottenham ended Chelsea’s 13-match winning run in the Premier League in January.
Kane – whose goal was his 25th of the season – believes victory next Sunday could yet derail the Blues’ momentum as they bid to retain their lead in the title race.
“It could be a big thing psychologically.” he 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.”
Spurs have now won their last seven games in the top flight, a feat they last achieved half a century ago. Kane went on: “Before the game we said it is important keep our momentum going.
“It doesn’t matter what anyone else does, we just got to keep winning games. We don’t want draws or to lose, anything to stop our momentum.
“Every game we go into now we have that mindset.”
