They've won just two matches, one for each bank of four - and both of those were away, which is a surprise for a team with arguably the best home support in the league.It's been a bit of a odd season for Spurs, too.
Kane and Spurs jumped back into the top four with a win over Wolves last week and will be looking to consolidate that place ahead of the global break as they take on Crystal Palace on Saturday.
But Pochettino retained faith in Foyth, which was repaid by the youngster by scoring a second-half victor at Selhurst Park.
"We were talking a lot in the week that, that [Foyth's errors in the last match] is football", Pochettino told reporters.
We understand we maybe need to sacrifice some players in some games so they can cope with the demand in the future.
"Juan deserves a lot of credit".
A change of shape midway through the first period helped the visitors take a strangehold of the game, with Dele Alli dropping deeper to influence the game on his first Premier League start in over two months.
"He's so clever. That situation can happen. If I decide not to play him - if he's fit but I decide not to put him in the starting XI or in the squad - and he's fit, you need to give him permission to go".
Argentine centre-back Foyth had conceded two penalties on his Premier League debut last weekend at Wolves.
"He works hard every day in training and he's come in today and got the victor".
As for Palace, they'll be without key man Wilfried Zaha as he failed a late fitness test due to a slight muscle injury.
Alli has been managing a hamstring problem, Dier has missed the last three games with a thigh injury and Eriksen has not fully recovered from an abdomen injury, yet all three have been called up by their countries for the games next week.
He said, "I had a few trials before I signed for Spurs so I knew full well how the system worked. Of course there's a gap and that can't be denied, but I don't think it's got to the situation where there's two different leagues".
