At the start of the season, all the talk was about Manchester City and Manchester United. The two teams that finished first and second in the Premier League last season were expected to pick up where they left off, and round two would commence.
Seven games into the season, and it isn't a Manchester club sitting at the top of the Premier League table, but a team from London.
Chelsea currently are on top with 19 points, four more than both United and City, who sit in second and third. The Blues have won six of their first seven matches, are undefeated this season and have only conceded four goals so far, considerably less than any other side.
Roberto Di Matteo's side slipped under the radar coming into the 2012-2013 campaign. The loss of Didier Drogba was considered massive, given the pivotal performances the Ivory Coast striker had given since he joined the club in 2004.
Yes, against the odds, Chelsea had won the Champion's League, but the style deployed to win the cup was negative and unattractive.
Yet this season, after some big name signings in the summer transfer window, Chelsea looked like England's answer to Barcelona. With the £32 million signing of Eden Hazard and another £25 million invested in Brazilian wonder-kid Oscar, owner Roman Abramovich has shown both his intent to back the manager he believed would only be a temporary solution and that the desire to own the Stamford Bridge based side still burns.
A formation change has been a massive part of the team's winning formula. Chelsea's new 4-2-3-1 has allowed the skillful trio of Hazard, Oscar and Juan Mata to support main striker Fernando Torres and overwhelm defences with their flair.
In the centre of the field Di Matteo has the choice of vice-captain Frank Lampard, the much improved John Obi Mikel, the creative Ramires and the youthful Romeu. Any combination of these four has so far proved successful for Chelsea.
The patient, fluent, one-touch style of passing now deployed by Chelsea is attractive and exciting to watch. Opposition so far this season have been passed off the park by the Blues, with no one yet able to combat Chelsea's rejuvenated side.
With main rivals United and City looking unsure, shaky and even poor since the start of the season, Chelsea and Di Matteo could not have picked a better time to take the Premiership by storm.
