Mauricio Pochettino's men have a reputation of giving up in big games and the midfielder feels they must learn to hold on to a lead
A frustrated Dele Alli felt Tottenham were justly punished for letting their lead slip against Manchester United in the FA Cup semi-final, insisting "we can't keep doing this".
Spurs deservedly took the lead 11 minutes into Saturday's encounter at Wembley when Alli pounced to turn home a cross from Christian Eriksen.
However, goals from Alexis Sanchez and Ander Herrera turned things around in London and sent United into the final, with Spurs now having lost in all eight of their most recent appearances in the last four.
Mauricio Pochettino's side suffered a similar collapse at home to Juventus in the Champions League last-16 second leg, with Giorgio Chiellini rather scathingly describing the result as "the history of Tottenham", adding "they always miss something at the end".
With their hopes of a first trophy since 2008 over for another season, Alli admits something has to change.
