The Spain international made a shock £50m switch to Stamford Bridge from Liverpool in January but did not have a great start to his career in West London.

Torres only managed one goal for the Blues and struggled to strike up an understanding with fellow forward Didier Drogba.

Even his opening months of the season with Liverpool were well below his prolific best, with the rigours of the World Cup taking their toll.

"For me the past season was the worst since I arrived in England," Torres admitted.

"The injury I sustained at the end the World Cup damaged my performance and made things more complicated than at any time in my career.

"Twelve goals in all in a season is nothing for me. Never during the season did I play to 100 per cent, neither for Liverpool or Chelsea.

"So I prefer to forget what happened. But I am not sorry I signed for Chelsea. I am convinced that when the Chelsea machine is at its full rhythm we will be very difficult to beat."

And Torres remains confident that with the benefit of a full pre-season alongside Drogba, the Blues will have a strike-force to be reckoned with in the coming campaign.

He added: "I do not have problems with Drogba. Sincerely, I am very connected with Didier. He is a sensational footballer and our possible rivalry is positive for Chelsea.

"I see many goals coming and that will give us significant success. Manchester United are the champions but I insist that we are the main candidates to take their title. The only thing I desire now are victories with Chelsea."
