Liverpool are sweating on the fitness of key players Steven Gerrard and Fernando Torres ahead of Tuesday's Champions League encounter away to Marseille.
Gerrard managed 22 minutes of Saturday's confidence boosting 2-1 win over Manchester United on his return from a groin operation.
But Spanish international Torres remained on the bench after suffering a hamstring injury against Aston Villa on August 31.
Javier Mascherano is also a doubt after pulling up with a calf problem in Saturday's game.
Liverpool are second in the Premier League and head to France on a high after manager Rafael Benitez saw his team record their first league victory over United in his fifth season in charge.
"Now we will go to Marseille in a good frame of mind," Benitez told reporters after Saturday's win.
"That was our best performance of the season and we now feel we can go into a Champions League in good heart and spirit."
Former European champions Marseille met Liverpool in the group stage last season, winning 1-0 at Anfield before being thrashed 4-0 at home.
