Leipzig were in the third tier of German football five years ago and are only playing their second season of Champions League football.

Benfica, who needed to win, had a two-goal lead going into the 90th minute.

But Emil Forsberg scored twice - including a 96th-minute equaliser - to send the hosts through.

Portugal midfielder Pizzi had opened the scoring for the visitors, who have never won a Champions League match in Germany in 12 attempts.

That run looked to be coming to an end when Carlos Vinicius doubled the visitors' lead.

But Sweden midfielder Forsberg completed a spectacular finish by Julian Nagelsmann's side - scoring with a penalty and then heading in Timo Werner's cross in the sixth of 11 stoppage-time minutes.
