Zenit St Petersburg advanced to the knockout stage of the Champions League despite slumping to a 4-1 defeat at already eliminated Austria Vienna on Wednesday.



Zenit finished second in Group G and qualified with a record-low six points, one clear of Porto, who lost 2-0 at group winners Atletico. Former two-time champions, Porto will now enter the Europa League.



Aleksandr Kerzhakov put Zenit ahead in the 35th minute before Philipp Hosiner leveled in the closing seconds of the first half. Goals from Tomas Jun on 48 minutes, Hosiner three minutes later and Roman Kienast in injury time gave Austria Vienna the win - the first for an Austrian team in the competition in almost 13 years.



"We deserved this victory though the scoreline is a bit flattering," Austria coach Nenad Bjelica said. "Zenit didn't play at their best but we did well to punish them."



Before kick-off, Greenpeace protesters entered the pitch carrying a banner, protesting against Russian oil drilling in the Arctic by Champions League sponsor Gazprom. Referee Aleksandar Stavrev, from Macedonia, interrupted the match for two minutes in the first half after firecrackers went off and fireworks were thrown from the Russian fan sector onto lower stands.



Zenit dominated possession from the start but Austria earned the first chance in the sixth minute when Hosiner was set up by Jun and forced Zenit goalkeeper Yuri Lodygin into a diving safe.



Zenit came close three times in two minutes but Austria keeper Heinz Lindner reacted quickly to shots from Hulk, Domenico Criscito and Cristian Anseldi.



Kerzhakov had a goal disallowed for offside in the 29th minute before putting Zenit in front six minutes later when he dribbled past Austria Vienna captain Manuel Ortlechner and goalkeeper Lindner.



Hosiner leveled with a Low shot in the far corner after loose defending by the Russians.



A lacklustre start to the second half proved costly for Zenit. Defender Markus Suttner's low cross from the left found the unmarked Jun in the centre, and Hosiner scored his second from a rebound after Lodygin couldn't control a thundering 25-metre shot from Florian Mader.



Zenit missed midfielder Danny through injury and lacked creativity to find openings in the Austrian defence.



Coach Luciano Spalletti brought on Andrei Arshavin for Konstantin Zyryanov in the 63rd minute but Zenit created hardly any danger, apart from a shot from Hulk that went just wide.



Ten minutes after coming on as a substitute, Kienast scored from close range in the third minute of injury time.
