Following the club's disastrous 5-2 defeat against Atletico Madrid in the Champions League last-16 first leg, Igor Tudor is now the first head coach to suffer defeat in each of his opening four matches in charge.
Goalkeeper Antonin Kinsky had to be withdrawn after 17 minutes due to two terrible errors as Spurs lost six games in a row for the first time in their history.
The supporters trust produced a stern statement after the clash, calling for action to be taken to turn the club around.
"The performance was a total disgrace and symptomatic of the abysmal state of things at Spurs right now.
“From the January transfer window to the management appointments, the lack of leadership and the total absence of anyone with a Spurs pedigree informing these decisions. Where is the Daring to Do? Where are the Echoes of Glory?"
“Emergency action is needed as right now we are sleepwalking off the edge of a cliff. Being a Spurs fan has never been so difficult but supporters will not sit by and watch the club continue to decline.
“At the very least those in Madrid should have their match tickets refunded. But all we really care about is that the club make us proud. We are here to support the team and be the 12th man. But we all deserve so much more.”
Tudor, who has been at the helm for just 25 days could be sacked before the side face Premier League champions Liverpool this weekend as the club desperately try to avoid relegation in the few games that remain this season.
