They were joined in the last 16 by Manchester United,Porto and Girondins Bordeaux,although four-time European champions Bayern Munich are on the brink of elimination after losing at home to the French champions. Maccabi Haifa,Besiktas,APOEL Nicosia and Atletico were all eliminated,but could yet finish third in their respective groups and go into the Europa League. There was high drama in almost all of Tuesdays eight matches with a flood of late goals and a superb 1-1 draw between AC Milan and Real Madrid. The Group C clash between the old rivals,who have won the European Cup 16 times between them,left both on seven points from four matches,just one ahead of Olympique Marseille,who crushed FC Zurich 6-1. At Old Trafford,Manchester United scored twice in the last 10 minutes to force a 3-3 draw with CSKA Moscow,stretch their unbeaten home Champions League record to 23 matches,and earn a place in the last 16. But individual honours went to Chelseas Drogba,back in Europe for the first time since being banned by UEFA for his antics against referee Tom Henning Ovrebo when they were eliminated by Barcelona in the semi-finals last season.

Although Aguero scored again to give Atletico a draw,Chelsea,with 10 points from four games,advanced from Group D with Porto,who won 1-0 at APOEL Nicosia with Falcao scoring the winner six minutes from time. United strike late Manchester United,seeking a third successive final,sealed a place in the last 16 the hard way. They needed two late goals from Paul Scholes and Antonio Valencia to force a draw with CSKA Moscow after trailing 3-1 with less than 10 minutes to play. The Russians raced to a 3-1 lead with goals from Alan Dzagoyev,Milos Krasic and Vasily Berezutsky after 47 minutes. But United,who scored through Michael Owen after 29 minutes,grabbed a point through relentless late pressure. VfL Wolfsburg,who won 3-0 at Besiktas,look favourites to progress. It was a bad night for Bayern,who went down 2-0 to Bordeaux after goals from Yoann Gourcuff in the first half and Marouane Chamakh just before the end. With Bordeaux advancing from Group A with 10 points and Juventus moving on to eight with a 1-0 win at Haifa,the Munich side,who have just four points,face a battle to qualify with a home match against Haifa and a visit to Juventus remaining.
