Diego Costa deal convinced Torres to leave Chelsea
Despite winning a UEFA Champions League, Europa League and FA Cup with the club, he never found the form he showed at Anfield and, after Chelsea recruited Costa this summer, Torres knew he needed to move on.
"Obviously I could see what the season at Chelsea was going to be. They signed a striker that was expecting to play and I need to have this feeling of being important," said Torres at his unveiling in Italy.
"After all these years, however, I needed a change, something that would give me the desire to play, to feel important.
"I'm happy to be here, I can't wait to begin. I played in La Liga and in the Premier League, now I am in the third most important league in Europe."
