Tottenham midfielder Dele Alli was left frustrated after their 2-1 FA Cup semifinal defeat to Manchester United.

The England international had given Spurs the lead inside 11 minutes, and despite dominating possession in the early exchanges, Mauricio Pochettino's side were unable to take the game by the scruff of the neck and force home their advantage.

"We let ourselves down," he told the BBC. “It's very disappointing. We have to try and pick ourselves up and finish the season strongly.

"You can't go 1-0 up and then 2-1 down against a team like Manchester United. We can't put ourselves in that situation.

"We were dominant from the first minute and it only looked to be going one way."

Alli admitted that Spurs cannot afford to keep throwing chances away.

"Everyone talks [about the club's need for silverware]. We want to win trophies, we have the staff that want to win. We can't keep doing this. We can't throw it away. We have got to improve."
