Liverpool plan to reassess Fernando Torres' medical care, after the Spanish striker injured his hamstring for the fifth time in 16 months.

Torres tweaked the troublesome muscle yet again in the Reds' 1-0 victory over Marseille in a Champions League match on Wednesday night.

Results of a scan indicate Torres could be out for another three weeks and Reds boss Rafael Benitez admits the recurring problem is deeply concerning.

"We are very disappointed with the situation," he said on the Sporting Life website.

"We have to analyse why it has happened.

"We have been working with prevention exercises in the past and still we have the same problem.

"We were taking time with him, he wasn't being rushed back.

"The time and training was all under control, as was all the exercises.

"We now have to analyse why it has happened again.

"The doctor and the physio were both working very hard with Fernando and they are both first-class, but now it is the same situation.

He added: "I have talked to Fernando looking for a solution, and also with the doctor and physio staff. We must solve this, it is not a serious injury, more one that is difficult to cure."
