The Light Blues had never overcome a 2-0 defeat away from home in the first leg of a European tie but after huffing and puffing in the first half they went ahead with a James Tavernier penalty just before the break. Striker Antonio Colak, who scored twice for Malmo at Ibrox a year ago to knock Rangers out of the Champions League qualifiers, headed in a second in the 58th minute to level the tie. More drama followed in the 78th minute when Malik Tillman, the 20-year-old attacker on loan from Bayern Munich, scored his first Gers goal with a header to turn the tie around and take the Govan side into the play-offs, with USG's Lazare Amani sent off in injury time.
