'Pool sweating on Keane fitness

Liverpool manager Rafael Benitez hopes Wednesday's 1-1 draw against Atletico Madrid will not prove costly to his side's title ambitions.

Robbie Keane, who scored Liverpool's goal to keep his side's Champions League hopes on track, was substituted near the end and is a doubt for Sunday's clash with Chelsea at Stamford Bridge because of a groin strain.

"It was a little bit of a muscle problem for Robbie," Benitez said.

"We need to check with Keane, he will see the doctor."

Chelsea and Liverpool have set the pace so far in the Premier League and only goal difference divides them at the top where they both have 20 points from eight matches.

Liverpool, who have not won a league match at Chelsea for nearly five years, are already without Fernando Torres and as well as Keane, they have concerns over Steven Gerrard and Xabi Alonso, who were also substituted in Madrid.

"The three players had some problems, I don't think they are too serious," Benitez said.
