I hope this hasn't been posted before. A good analysis by Robbie Savage can be read here. Best parts: "Chelsea have not really clicked this season but they are in the top four and two points off the top of the table. They are not where they are by playing fantastic football but you have to say they are very well placed because that group of players will undoubtedly have a spell this season where they click as a group. And at the Emirates Stadium on Monday, when I compared the teams and looked at both benches, I would have to say they looked more like potential champions than Arsenal did. The bottom line is that the spine of the 2013 Chelsea team is not as good as the 2004 side. Didier Drogba has gone and the players that remain - from Frank Lampard in midfield to John Terry in defence to Petr Cech in goal - are aging.This Chelsea side is not as strong as the one that Mourinho had during his first spell at Stamford Bridge, when he won the league twice in three seasons between 2004 and 2007. I have talked before about how bizarre it was for Mourinho to loan out Romelu Lukaku this season and, clearly, signing a new striker in January would increase Chelsea's title chances massively."
