Fernando Torres is making good progress in his recovery from his latest injury setback ahead of Sunday's Merseyside derby, according to Liverpool's head of medical Peter Brukner.
The Spain striker limped out of the 2-1 defeat by Blackpool ten days ago with an adductor muscle problem.
However, he has provided under-pressure manager Roy Hodgson with a timely boost after making a return to training.
Torres has struggled with a succession of injury problems during the past 12 months.
The Reds travel to Goodison Park for a massive derby encounter with Everton on Sunday.
Both clubs are struggling towards the foot of the Premier League table following disappointing starts to the season.
"Fernando is doing pretty well. He had a slight tear in one of his adductor muscles very early on in the game against Blackpool that prevented him going away with Spain in the internationals," head of sports science and sports medicine Brukner told the club's official website.
"He has had intense treatment over the last ten days and responded very well to that treatment.
"He's ready to resume training today and if we can build up his training and get through the next few days, then we are optimistic but not certain that he will be able to line up against Everton.
"It's still early days but so far so good. He has responded well to the treatment but we will just have to wait and see whether he is able to build up his training sufficiently.
"He'll join in the full training session on Thursday, then build up Friday and Saturday. If he gets through these sessions and he is able to stretch out fully and has no after effect from the sessions then he will be able to play.
"So we are optimistic he will be ready but it's still too early to say for sure."
