Fernando Torres has vowed to stay at Chelsea and recapture the form that earned him a £50m price tag.
The Spaniard has struggled since his big-money move from Liverpool in January 2011, with former team-mate Didier Drogba and now Demba Ba the oft-preferred striker.
A brace in Chelsea's 3-1 Europa League win over Rubin Kazan in midweek hinted at the player of old and Torres admitted he is desperate to rediscover the goalscoring touch that saw him net 65 league goals in 91 starts at Anfield.
"I want to do the things I used to do all my life," he told the Daily Mail.
"I did them at Atletico, I did them at Liverpool and I am not doing them at Chelsea. I am working on it. If I knew the reason, I would fix it in one minute. But the only way to fix these things is to work at it.
"I am training every day and I will never, ever give up.
"I am happy here. I am enjoying London and happy at this club.
"I know my statistics at Chelsea have not been the same as in other years in my career. But I am fighting to get back to those statistics and I will never, ever give up.
"I will try my heart out for this club. There are too many things I have to give back to these people and I want to show my thanks to them.
"Hopefully this season we can give them two more trophies and next season we can fight again for the biggest ones, the Champions League and the Premier League.
'I am getting better but I'm still not at the level I want."
