Much was expected of the 29-year-old when he swapped Merseyside for London on deadline day back in January 2011, but the Spaniard has been a real disappointment in comparison to what the Blues' supporters may have been expecting.
Just 16 league goals in 89 appearances have come so far for Torres, but there is a sense that he is improving with every game in a Chelsea shirt.
He's scored five goals in 11 games in all competitions—a strike rate that would see him better last season's total of 23 goals—and has therefore enjoyed the start to the season he would have liked.
The issue for him seems to be in the Premier League, with just one of his five strikes this season coming in seven appearances. Nevertheless, people are talking about a rebirth, or resurgence if you will, and only time will tell if Fernando Torres has the mentality to return to his best form.
Here are six reasons to show why it has come about.
Whether you're a Liverpool supporter who dislikes Torres, a Barcelona fan who simply cannot stand anyone from the Spanish capital of Madrid or even a Chelsea fanatic who prefers Samuel Eto'o in attack, one cannot deny Torres his place based on his level of effort.
Chasing down the opposition's defenders is a required trait of the modern-day striker; it helps the team regain possession and ultimately shows a willingness to fight for each ball. And that's exactly what the former Atletico Madrid man does. He chases every ball down and, while he might not always make a decent challenge, the effort put in means he is respected by his team-mates.
Juan Mata recently went on record to praise his friend and colleague's work rate, via Yahoo Sports: "He deserves it. He’s trained very hard, very professionally and now he is scoring it has brought the confidence back."
Jose Mourinho is an admirer of work rate in particular and this has been the reason for Torres' extended run in the side. Currently out injured, he will be raring to get back into action as soon as possible and back amongst the goals.
Various analysts in football suggest that players—and particularly strikers—base their game on confidence to the extent that a lack of it would indicate a dip in form.
For example, if Torres scores four goals in a row, his confidence is high and therefore other factors change with that, such as how much the opposition will focus on his threat.
But when you're as low on confidence as the striker had been for the previous two years of his Chelsea career, it's difficult to get back to a similar level. However, Torres has been fortunate in that he has had the unrelenting support of the fans, who want to see him become a success, and his team-mates.
Now under the wise head of Mourinho, the 106-cap Spain international clearly has a new mental state and seems to take every game by the scruff of its neck. And that can only be a good thing for the Blues manager.
It seems to be a reoccurring theme under the 50-year-old coach that the majority will praise his methods, and, of course him, as the best they've ever worked with. There are, no doubt, going to be some exceptions.
But Torres is firmly in the good books, despite what the papers may have speculated in the summer. This was highlighted with his performances against Bayern Munich, Manchester City and Spurs, and the notable thing about the forward is that his best performances this season have been against the better teams.
The belief that the world-class coach instils in his players is something to be admired, and be assured, it's no coincidence that the players soon begin to get results on the pitch once Mourinho works his magic. Torres hasn't just benefited, he's grown into a better player as a result.
Playing to Strengths
Rather than get David Luiz or John Terry to loft a 60-yard pass towards Torres, which is both easy to judge the flight of and to defend against, it's perhaps wiser to play the ball into feet.
No doubt, his aerial ability is fairly impressive. But coming up against strong defenders such as Nemanja Vidic, why not let Torres trouble them with the ball at his feet instead?
Under Mourinho, there's been a noticeable change in the supply to Torres. What used to be pointless aerial balls now consists of passes into feet and into the channels, where he can exploit the lack of mobility in the opposition defence.
It's no wonder then that when this has happened, Torres has scored five goals and created a fair amount, too.
For all his efforts and attempts at goal, sometimes it just wasn't meant to be. Torres was denied a wonderful hat-trick against Schalke as his header bounced off the bar, settling for a brace instead.
But his opener—a header at the far post after a knockdown—showed that he will eventually gain a slice of good fortune if he continues to get in the right positions.
The feeling is that you can only try so hard so many times and fail, and Torres is beginning to reap the rewards for his patience, as are the fans.
Ask any footballer what their motivation for playing is and the generic answers will naturally follow. Themselves, their family, the money (they don't mention that one but it's obvious) and, finally, the fans.
And rightly so. The fans pay to see them in action, not only giving up their spare time but actually directly funding the players' wages. So in turn, the players have an obligation to provide a performance for the supporters.
Even when Torres wasn't firing at all, the supporters remained behind him. That was despite the fact that the media were laying into him and his manager Andre Villas-Boas failed to support his efforts for the team.
Eventually the footballer comes through with the right support. And Torres, while not yet completely revitalised, is certainly on his way. If he continues on the right track, the supporters will certainly see their faith repaid in no time.
