Tottenham Hotspur's calamitous season hit a desperate new low as goalkeeper Antonin Kinsky was taken off after only 17 minutes in a humbling Champions League capitulation at Atletico Madrid.

Kinsky, in for Guglielmo Vicario, twice lost his footing to gift goals to Marcos Llorente and Julian Alvarez – after which he was taken off by interim head coach Igor Tudor.

In between, Micky van de Ven also slipped to allow Antoine Griezmann to score before Robin le Normand added a fourth after only 23 minutes of some of the most remarkable Champions League action of recent times.

Pedro Porro's goal was only an interruption to Spurs' misery, Alvarez adding his second 10 minutes after the break with a lightning counter following Jan Oblak's stunning save from Richarlison.

Tudor will now faces more questions about his future after a fourth-successive loss as the Croatian fails to arrest this rapid descent into crisis.

Kinsky's hopes of staking a claim ahead of Vicario were shattered after only six minutes when he slipped, sending the ball straight Ademola Lookman, who found Llorente for a composed finish.

It was the start of a mind-blowing passage of play which was embarrassing even in this shocking season for Spurs.

Van de Ven was next to lose his footing to present Griezmann with a second before the hapless Kinsky fell to the floor once more when attempting to clear, allowing Alvarez to walk the ball in.

Tudor had seen enough, putting Kinsky out of his misery sending on Vicario, the 22-year-old Czech being consoled by team-mates, even receiving sympathetic applause from Atletico fans.

The agony was not over for Spurs as Le Normand added a fourth after 22 minutes following a scramble before Porro pulled one back with a low finish.

Atletico keeper Jan Oblak also suffered his own nightmare with clearance, sending one straight to Dominic Solanke to score again for Spurs.

The night however finished on a further worrying note for Spurs. A late clash of heads between between Joao Palhinha and Cristian Romero led to Palhinha being taken off while Romero appeared to still be affected as they finished the match a man down.

If Igor Tudor believed his brief losing reign could not get any worse after the home defeat by Crystal Palace, he reckoned without one of the most humiliating nights in Spurs' recent history.

The Croatian was bold with his team selection, especially dropping regular first choice Guglielmo Vicario for young deputy Antonin Kinsky.

To say it was a move that back-fired is a masterpiece of under-statement as Kinsky suffered the sort of personal nightmare that will take huge strength of character to recover from.

Even the hearts of Atletico's passionate, partisan support went out to Kinsky as his number came up following his errors, with team-mates also moving to offer words of comfort as he went off.

Tudor was in optimistic mood before the game, but that all changed inside 23 madcap minutes as Spurs slipped – literally – from one costly error to another, effectively ending this contest and, in all likelihood, the tie.

Spurs actually created chances of their own as Atletico stepped off the gas, but the damage was already done.

And it may be permanent damage for the beleaguered Tudor, who arrived as an emergency measure with a reputation for having an instant impact in his chequered coaching career.

Instead, things have arguably got worse and now, with a testing trip to Liverpool on Sunday and Spurs just one point off the Premier League relegation places, the club's hierarchy look like they will soon face another decision of huge significance in a bid to somehow rescue a season in freefall.
