"To be honest, since I've been at Palace it's been these games that we've relished and we've always done well against them", he said.
The Spurs boss also gave his view on the recent performance of Kane while saying "He wants to score, he is so determined to score goals".
The result leaves the Eagles 16th, only out of the relegation zone on goal difference, while fourth-placed Tottenham are two points behind leaders Manchester City, although the top three are all in action on Sunday.
"I've compared him with Gabriel Batistuta because his mentality is similar".
In last week's fixture at Wolverhampton Wanderers, Foyth conceded two penalties to put Spurs' eventual 3-2 victory and his reputation at risk.
"When you are a centre-back you are involved in this type of situation but the confidence and the trust is massive from us".
Pochettino added: "Today he showed great personality and he played so well, like one week ago. I say again to our fans be patient, because it is going to be fantastic".
"He's so mature, (he) is a player for me that has all the potential to be one of the best centre-backs in Europe".
It's a good sign that the North London club are still on the main winning games and everything could be falling into place for them, as key players return from injury.
They instead secured their third win in eight days, and worsened Palace's misery on an evening when they had again struggled in the absence of the injured Wilfried Zaha.
Spurs were dealt an injury blow when Kieran Trippier limped off midway through the first half with a groin injury, but Pochettino is hopeful he could still be fit for England's upcoming internationals with the United States of America and Croatia.
- Palace have lost seven consecutive top-flight matches against a single opponent for the first time ever.
They have lost nearly all their big games and have been nowhere near their seductive best, yet they are still in the Champions League, just about, and a win today would take them to within two points of the leaders Manchester City.
While Lloris had threatened another in a series of errors earlier in the game, the Spurs captain stepped up in the final 10 minutes to make a trio of saves, firstly pushing away a powerful swinger from Jeffrey Schlupp's right foot.
