"It's exactly what we needed," Kane said. "It was a great performance with a lot of energy, plenty of goals and a clean sheet.
"It was almost the perfect night. It can't stop here, though, it was a game we were expected to win.
"We have a very tough game on Sunday and hopefully we can take this momentum into that."
Admitting Spurs are playing catch-up as they prepare to head to Anfield, Kane added: "Of course we know in the Premier League we are far behind and have a lot of catching up to do.
"Sunday will be a tough game. They have started the season very well so we have to make sure we put in a performance similar to Tuesday.
"Any top game in any top competition there are fine margins between winning and losing and we probably haven't had the rub of the green this season for one reason or another.
"But that is part of the game, we have to overcome that. Performances like this will definitely help but it is about the next one."

Despite the victory, Mauricio Pochettino says he still expects more from his side, following defeats to Bayern Munich and Brighton and a home draw against Watford.
"The pressing was there but not as much as I want," Pochettino said. "I want more. We'll get there. It's a massive experience for us as a group that has never lived this type of situation before.
"This type of situation should help us to get stronger. We have three games ahead in Belgrade, Munich and here against Olympiacos. It's in our hands and we're in a better position that last season."
