All the latest news and views from Stamford Bridge.
Jose Mourinho has spoken of his desire to continue to evolve his own tactics.
A staple of a Mourinho-led Chelsea, or Internazionale, was a defensive rigidness, typified no greater than when the Treble-winning Inter side nullified what was, at the time, considered one of the best club sides ever-assembled over two legs in Champions League competition.
In 2010, en route to their successful campaign in Europe, Inter beat Barcelona 3-2 on aggregate.
For fans of containment, of organised footballers from back to front, it was a victory but for supporters of tiki-taka magic it was an injustice. Regardless, post-match, Mourinho lauded it his greatest triumph and it arguably punctuated his managerial style perfectly.
Upon his return to Chelsea earlier this year, though, the Blues were no longer really a true Mourinho team. Gone were hulking bruisers like Didier Drogba, Frank Lampard had aged in years and the Stamford Bridge midfield was blessed with technically-exquisite creators.
Using his Real Madrid experience, Mourinho has confessed he is moving away from his 1-0 desires into a philosophy that embraces attacking-spirit and this is largely because of the players he now calls his; guys like Eden Hazard, Juan Mata, Oscar et al.
As quoted by BT Sport, Mourinho said: 'If I want to win 1-0, I think I can. One of the easiest things in football is to win 1-0. It's not so difficult. You structure your team from the back, you organise your team from the defensive idea, you don't give freedom to your players to express themselves.
'The dynamic of the team is defensive and what you do is you recover the ball and try to punish the opponent on the counter-attack. To win 1-0 is not the most difficult thing in football.'
He added: 'I don't want to because we are going in a direction which is the right direction in terms of the quality of football we want to play, and it's quite frustrating that you have to change that and go one step back and go in another direction just because you want better results.'
One player who may frustrate a coach - not necessarily Mourinho - is Eden Hazard as, according to a report in the Daily Mail, the Chelsea staff are worried about his lack of trying. The man's skill-level is not in question, neither is his obvious contributions, but it is his effort-levels that are cause for concern.
Hazard has a pass accuracy of 85%, wins 75% of his tackles, has won 43 fouls, completes 21% of his attempted crosses, hits the target with 70% of his shots, has scored six times, assisted four times and created 40 clear-cut chances in 1,326 minutes of Premier League football (16 appearances in total).
As statistically-impressive as Hazard is, one has to wonder how much more he could give if he wasn't the first to leave the training ground in order to have lunch, and the first to leave in order to go home in the afternoon.
