Tottenham's mentality was questioned as assistant boss Cristian Stellini apologised for their humbling by Leicester City.

The Foxes were hugely impressive as they came from behind to win with four goals for the second time in a row.

Spurs, with boss Antonio Conte back in the dugout following a gallbladder removal, had an ideal start when Rodrigo Bentancur diverted home Victor Kristiansen's sliced clearance.

But the resurgent Foxes netted twice in less than two and a half minutes to turn the game on its head.

First Nampalys Mendy scored only the second goal of his entire career when he crashed a first-time screamer into the top corner from the edge of the box.

Soon after, Wout Faes' tackle on Harry Kane on halfway ricocheted into the path of Kelechi Iheanacho, who squared for James Maddison to score.

Spurs defender Eric Dier stood off Iheanacho, who stroked a shot into the bottom corner for a Leicester third before the break.

Harvey Barnes had a goal disallowed by the video assistant referee for offside but Spurs failed to learn their lesson and the winger slotted in a fourth from Maddison's pass 10 minutes later.

"To be consistent is a long process, it's a mental process, you have to be better mentally," said Stellini, who spoke to the media instead of the recovering Conte.

"After we scored the goal, something changed. In the team something has to change, not individually. It's about the desire.

"We have to apologise because our performance wasn't good enough. We have lost too many tackles, too many duels. This comes from strength inside of you."

To cap off a truly rotten afternoon for Spurs, they lost goalscorer Bentancur to a knee injury suffered as he tackled Mendy after an hour.

The Foxes are now 13th, six points above the relegation zone, while Tottenham remain fifth.

Tottenham had appeared to turn a corner after a team meeting following their 4-2 loss at Manchester City a month ago.

Wins over Fulham, Preston and champions City came afterwards.

Conte missed that City win as he recovered in Italy and he probably wishes he was still at home after witnessing this capitulation up close.

First-choice goalkeeper Hugo Lloris missed the first of many games here, with the club captain ruled out for at least six weeks with a knee injury.

Veteran Forster started in goal, only his second league game since joining Spurs in the summer.

It was all looking so good when Bentancur scored - although they had to wait two minutes to celebrate after a long VAR check for offside.

But that was one of just four shots on target all afternoon.

Kane, their all-time top scorer, had to wait until the 90th minute for his only shot of the game. Son Heung-min, who scored a hat-trick in the reverse fixture, only had one effort himself.

Pedro Porro, their new signing at right-back, had a disappointing debut as he struggled with Barnes' pace.

Bentancur added to an already long injury list when he was hurt in a collision with Mendy and needed oxygen - although he was able to walk off with help instead of needing the stretcher that had been sent on.
