Mauricio Pochettino will take the positives out of Tottenham's Europa League exit after a 2-1 defeat at home saw Spurs lose 5-1 on aggregate to Borussia Dortmund in the last 16 of the competition.

Having been beaten 3-0 in the first leg, Pochettino's side was hoping for a miracle in front of its own fans at White Hart Lane on Thursday.

But a fine long-range strike from Pierre-Emerick Aubameyang midway through the first half put the tie beyond Tottenham, with the Gabon international adding a second goal for the visitors in the 71st minute.

The hosts did get a consolation from Son Heung-min, who made the most of Neven Subotic's weak back pass to round goalkeeper Roman Weidenfeller and score, but they can now focus on their bid to win the Premier League.

"I'm very disappointed we're out of the Europa League, but we need to recognize we played against a very good team [playing at] a Champions League level, because Borussia Dortmund are one of the best teams in Europe," Pochettino told BT Sport. "I think we improved a lot, learned a lot from last week in Germany. We competed and we need to take positives.

"We have a lot of young players that need to feel what it means to compete in Europe and I think for the team it was a good test and we can take positive things."

Midfielder Ryan Mason said Tottenham had simply left itself with too much to do after conceding three goals without reply in Germany.

He also praised a Dortmund side that is yet to lose in 2016 and has now won all four of its knockout ties in the Europa League this season.

"The first leg killed us," Mason said. "The tie was over to be fair. We didn't do ourselves any justice. We didn't go there and get our philosophy across. We were punished big time by a top side. There's no doubt about that – they're a top side."
