Liverpool striker Fernando Torres faces another spell on the sidelines with injury and admits this recurrence of a hamstring problem is something of a worry. The Spanish star could be out of action for three weeks after suffering his injury in Wednesday's UEFA Champions League win over Marseille.

"I am a little disappointed, but all I can do is move forward," Torres told the club's official website.

"It is worrying me because it has happened a few times.

"After this latest injury the important thing is to recover without rushing a comeback date and trying to make sure it does not happen again."
