Fernando Torres believes he is now getting back to full fitness as he puts in extra hours to help get Liverpool's season back on track.
Liverpool have struggled in the league as well as exiting the Champions League at the group stage and have been hampered by injuries to key stars like Torres and Steven Gerrard.
However, both players have returned to action in recent weeks and, while Torres has looked short of fitness at times, the former Atletico Madrid striker is convinced he is finally getting over the effects of the groin injury that kept him out of six matches in November and December.
"I am good now," he said. "Much better than a couple of months ago. I need to keep working three, four or five hours more than the rest of the squad because I need to keep recovering for the rest of the season.
"One of the reasons I'm working really hard is because I know in this situation Liverpool need every player fit. It's a difficult time but it's worth it if I want to play. I do the normal training session with my team-mates but before and after I have to do treatment, exercises and gym work to make my leg strong enough.
"We are doing a good job and I'm feeling nothing bad in my leg. I have been able to play 90 minutes in the last four games so I'm really happy with the progression. Maybe I'll have to do this all season."
He added: "It's frustrating because I've never been injured before - not at Atletico and only one small one during my first season here. The last two seasons have been the first time I've had consecutive injuries.
"Always when the team is not in the best moment it's frustrating if you can't help your team-mates. It's really hard watching the games from the stands.
"I'm not old but I'm not that young, so I need to look after myself with extra work. I know I have to work harder in order to play three games a week until the end of my career. I need to work harder than before."
