Last season, Jose Mourinho described Chelsea as "little horses" and underlined the need for top strikers in their team.
So he got rid of all his misfiring strikers and brought in players with top credentials to fill the gaps in his near perfect team.
Mourinho solves problems
He brought in a proven playmaker in the form of Cesc Fabregas, filled the need of a lethal striker through Diego Costa and filled the void in defence left by David Luiz through Filipe Luis.
Not only that, they brought one of the best goalkeepers in the world Thibaut Courtois to replace another one, Petr Cech.
Everyone expected Chelsea to challenge for the title this season. Until now, they've certainly looked potential title winners being unbeaten both domestically and at the European level.
Chelsea playing good, effective football
They've put in dominating performances against top teams and have done that without resorting to a tactic close to the Special One's heart: 'Parking The Bus'. They've played free flowing and dynamic football, scoring a lot of goals along the way.
Costa and Fabregas have been the main contributors towards this change in Chelsea's philosophy. They seem to have struck up an instant rapport both on and off the pitch and have been assisting each other on the pitch to score goals and break records.
Chelsea have no weaknesses
In hindsight, Chelsea don't seem to have any weaknesses. Their defence is solid with experience. They have wing-backs who realise that they have to defend as well, something that is all but forgotten in other teams.
Their midfield has just about the right amounts of creativity and industry. Their strike-force has become arguably the most lethal in Europe with Costa in it.
So for me, Chelsea certainly start as one of the favourites to win Champions League this season.
