Red Bull Salzburg scored four times in 20 minutes to stun Lazio and make it through to the Europa League semi-finals.
Trailing 4-2 from the first leg in Rome last week, Salzburg then went further behind when Ciro Immobile scored his 39th goal of the season for Lazio 10 minutes into the second half.
However, the hosts rallied as Munas Dabbur, Amadou Haidara, Hwang Hee-chan and Stefan Lainer all scored in quick succession to earn Salzburg a 6-5 aggregate success.
- 5/6 Atletico Madrid
- 9/4 Arsenal
- 13/2 Marseille
- 7/1 Salzburg
Tournament favourites Atletico Madrid also advanced to the final four, despite a 1-0 loss to Sporting Lisbon in Portugal.
Colombian Fredy Montero's header from a far-post cross in the first half gave Sporting some hope against a team that had won 13 of their previous 15 contests in all competitions.
Antoine Griezmann squandered two great opportunities in the second half to ease Atletico's nerves, yet they were able to hang on anyway and won 2-1 across the two legs.
