His eye-catching displays have seen Torres linked with a host of the continent's biggest sides, with Chelsea in particular rumoured to be lining up a £50million swoop.
The 24-year-old added: "It's been quite easy for me. I have been able to enjoy every minute at a club where things have gone well.
"I have been part of a team where every player shares the same goals and where a player can rely on the support of his team-mates.
"I have also worked with a manager who believed in me. It was the combination of all these factors."
