Noah Okafor scored the only goal as RB Salzburg claimed a 1-0 victory over 10-man Sevilla at the Red Bull Arena on Wednesday to progress to the knockout stages of the Champions League for the first time in their history.
Salzburg finished as runners-up in Group G with 10 points from their six matches, one behind pool winners Lille. Sevilla ended in third place and will play in the Europa League playoff round.
The first half had little goal-mouth action but the game burst into life after the break as Salzburg were helped by a second yellow card for Sevilla's key midfielder Joan Jordan on 65 minutes.
The match was played behind closed doors without fans due to heightened COVID-19 restrictions in Austria, so the hosts were unable to celebrate their achievement with their supporters.
"I will certainly never forget this game, it is unbelievable what we have achieved over 90 minutes today," Salzburg captain Andreas Ulmer told reporters.
"Everyone supported everyone, and the players who came on as substitutes were also very important. This is a very big moment for Austrian football."
For two sides with reputations as attacking teams, it took 35 minutes of cagey football for the first shot on target as Ivan Rakitic warmed the palms of Salzburg goalkeeper Philipp Kohn.
It was the only occasion when either keeper was tested in the first half, though Sevilla defender Jules Kounde headed wide from a corner with the best chance of the opening period.
Sevilla should have been ahead minutes after the break when Munir El Haddadi had a free header six yards from goal but saw his effort come back of the crossbar.
It was a big chance the visitors would rue missing as Salzburg went up the other end and scored with an excellent team goal.
They finally managed to string passes together and Karim Adeyemi was worked into space on the left. His low cross into the box was turned in by Swiss forward Okafor.
Sevilla's night got worse on 65 minutes when Jordan received a deserved second booking for pulling back the pacey Adeyemi and they were left needing to find two goals with 10 men.
Salzburg were able to comfortably hold out to the end, with Rakitic's first-half shot the only one Sevilla, who are second in Spain's LaLiga, could muster on target.
