A hard fought 2-0 win over Hull was enough to take Jose Mourinho's men above Arsenal - for a day at least. A tough first half saw both teams look dangerous, but Eden Hazard's goal settled Chelsea's nerves and they were rarely threatened before Torres sealed the victory late on.
Here's five things we learned about Chelsea following this victory:
While Chelsea keep getting results with the Spaniard on the bench, it's hard to see him getting back into this team. Mata could undoubtedly bring something to Chelsea's attacking play, being at least as threatening as Hazard if last season's statistics are anything to go by - but with Willian seen by Mourinho as a more natural and harder-working winger, there may just be no future at the club for the former Valencia man.
David Luiz might be employed in midfield from now on
After appearing reluctant to pick the Brazilian in a defensive midfield spot for much of the season, the last couple of games have seen Luiz impress in a position that has less defensive responsibility than at centre back, while also allowing him to occasionally come forward. With Cahill looking strong alongside Terry, this might be the only Chelsea first-team spot available, and is one that Luiz appears happy to make his own.
Hazard is the one world class player at the club
Eden Hazard looks like the sole superstar at Chelsea - the one player in the side fans can look to for something special to win games. Looking through the Chelsea squad, there are plenty of players that at one point or other were among the top three or four players in the world in their position, but given that many of these are the wrong side of 30 - while others have lost their starting place to a young pretender - it's hard to pick any other truly world class player. This will undoubtedly be something Mourinho will seek to remedy in the summer.
Fernando Torres - back to form ?
After scoring for the second Premier League game in a row, and with the striker looking like the Fernando Torres of old, is this the start of the Spaniard's return to goalscoring form ? It's kind of difficult to say - Torres was hard-working but on the periphery for much of the game, more willing to help his team mates than grab a strike on goal. Having said that, he managed to take his one chance on goal, bursting through and emphatically smashing in at the near post.
The nature of his goal if anything should encourage the Spaniard to play with courage, confidence and a bit more greed - three qualities present in all top class goal scorers, and qualities Torres possessed himself earlier in his career. The problem with Torres, however, is that he has almost convinced himself that being the workhorse that leads the line and helps the team to win is good enough - but, for a £50 million striker, it's not.
Top of the league, transfer window open - should Chelsea strengthen ?
With Chelsea now in pole position in the Premier League, are there any positions they should look to strengthen ?
Mourinho has already come out and said that Chelsea are unlikely to dip into the transfer market this month, but injuries to Frank Lampard and Branislav Ivanovic means that the squad isn't as strong as it could be. A specialised left-back would surely be a must if Cole leaves in the summer - given that Cesar Azpilicueta, though playing really well there, is a right-back by trade. Likewise, long-term replacements for Terry and Lampard surely remain on the agenda, while a world class striker is the most obvious addition - if one can be found.
