Kenny Dalglish believes Craig Bellamy must be handled carefully if he is to avoid another serious injury.
The Wales striker is keen to play in every game he can, but the Liverpool boss feels a more restrained approach is needed.
Bellamy has made just nine starts in all competitions this season, but has come off the bench 11 times.
And the Reds boss will continue to adopt this approach for the rest of the season in hope of the striker avoiding another serious injury.
"Some players need greater management than others, but the players themselves have got to look after themselves," he said.
"Craig is fantastic in preparing for matches. I'm sure there's many others out there exactly the same - but he's really got a great knowledge of how you prepare.
"Some can go for longer, further, harder than others. We just want them to give themselves the best possible opportunity of performing as best they can.
"We can't run people into the ground, so we have to try and manage how they get on the pitch and how long they are on it.
"For the fitness side of it it's not fair on too many players at this stage of the season to be starting them every single game.
"Our goalkeeper, Pepe Reina, obviously, has started every one - but for the outfield players, it's difficult to get them through every game you play."
