The Spaniard says Gerrard should not rush back from his hamstring injury.
Gerrard suffered the injury in the FA Cup replay defeat to Everton earlier this month and the club is hopeful that the skipper will be ready for their clash with Real Madrid.
“Stevie doesn’t have a substitute at Liverpool,” said Torres.
“Stevie is the lad every great side has – our leader, the one-club man.
“But I know from experience hamstring problems are risky. If you get one there’s nothing you can do but let it repair.”
