With Bordeaux advancing from Group A with 10 points and Juventus moving on to eight with a 1-0 win at Haifa, Bayern with four points, face a battle to qualify with a home match against Haifa and a visit to Juventus remaining.

The Group C saw a clash between AC Milan and Real Madrid, who have won the European Cup 16 times between them.

The 1-1 draw left both on seven points from four matches, just one ahead of Olympique Marseille who crushed FC Zurich 6-1.

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.
