Benitez revealed that Torres, whose injury-time winner resulted in him overtaking Roger Hunt as the quickest Liverpool player to reach 50 league goals (in 72 games) for the club, has more recently been troubled by an ankle injury.
"Fernando has had some problems with his ankle more than his groin and he has been working very hard with the fitness coach and the physio," added Benitez.
"It depends on how he feels - in terms of how many games he can play - but against Villa he was OK.
"We will have to assess things and see what happens. We will leave it with him but we need to keep him fit for the remainder of the season. That is the important thing."
