Tottenham star Dele Alli believes the team must show more maturity if they are to close out tough games.

Spurs raced into a two-goal lead against Arsenal in the North London derby.

But they could not sustain their performance level and were pegged back for a 2-2 draw.

In fact, great saves from Hugo Lloris are the only reason they did not lose the clash.

"Being 2-0 up we have to be more relentless defensively and a little more mature in the way we played in the second half," the 23-year-old told Sky Sports.

"We knew with Arsenal getting the goal before half time they were going to come out and push for the second goal, which does create space for us to counter-attack.

"But at the same time we have to be cleverer with our defending and we're obviously disappointed.

"I think the boys played very well in the first half. Obviously this isn't an easy place to come, you just have to be a bit cleverer with the way you play.

"But we showed great character to not lose in the end because of the amount of possession they had. They are a talented team.

"Obviously we are disappointed but there are a few positives to take."
