The most prolific goalscoring spell of his career, he became the fastest player in Liverpool history to score 50 league goals. Torres left the club in January 2011 to join Chelsea for a British record transfer fee of £50 million, which made him the most expensive Spanish player in history.
In his first full season at Chelsea, Torres won the FA Cup and the UEFA Champions League, despite receiving criticism for a comparatively low goal-scoring record.
So aggressively do both sides chase each other down, none of the players appears to have any room in which to manoeuvre; the moment they gain possession an opponent snaps in at their shins.
It is no wonder, when it comes, that the match is a testy, bruising encounter, the tension thickening the air inside Liverpool’s Anfield stadium.
The middle of October, and it is a tricky period for Liverpool Football Club.
For the first time in more than 20 years they have lost four consecutive games.
Three of Torres' former clubs - Liverpool, Chelsea and AC Milan - tweeted good wishes to him, as did former Blues team-mate Didier Drogba.
Drogba, who together with Torres won the Champions League for Chelsea in 2012, tweeted: "Get well soon Champion Torres".
