Five berths in the round of 16 in the UEFA Champions League will be on the line on Tuesday. Marseille, only 13th in France's Ligue 1, can clinch a berth in the knockout phase of the UEFA Champions League with a win against Liverpool at the Stade Velodrome. OM, which has won all six home games it's played against English clubs, will also advance with a tie unless Besiktas wins at Porto. Liverpool will probably be knocked out unless it wins. In Group C, all four teams remain in contention, though the top two teams, Real Madrid and Olympiakos, are both at home.
