GROUP C:Champions League debutants Malaga stunned seven-times winners AC Milan when Joaquin made up for missing a penalty with the winner in a memorable 1-0 victory.
After Kevin Constant had brought down Jesus Gamez on the edge of the area, former Spain winger Joaquin drove his 44th-minute spot kick high towards goal but it skimmed the top of the crossbar and flew off into the crowd.
However, the 31-year-old crowd favourite made no mistake in the 64th minute when played through by Manuel Iturra and his low shot beat Milan goalkeeper Marco Amelia and went in off the post to give Malaga an impressive three wins out of three in the group.
With three of six matches played, Malaga have nine points, with Milan on four. Zenit St Petersburg have three after their 1-0 win at home to Anderlecht, with the Belgian side on one.
Alexander Kerzhakov calmly converted the 72nd-minute spot kick for his 200th career goal as Zenit withstood late pressure from the Belgian champions to record their first victory.
