Liverpool's Italian midfielder Alberto Aquilani is a doubt for the clash with Lille on Thursday and Manchester United on Sunday.
After gaining the plaudits from the boss for his recent displays and completing his first 90 minutes of Premiership action against Portsmouth on Monday Aquilani was expected to start on Thursday.
Instead he missed training on Wednesday after picking up a virus and looks very doubtful for Thursday's match which will be a big blow to the player who was just starting to make his mark after a difficult season.
"He has a virus and is struggling with his fitness," Rafa Benitez told the club's website.
"We have to take care of him and decide tomorrow. It will be a late decision."
