If you think the Blues' summer transfer dealings are done there though, think again. The Londoners haven't won the Premier League title since 2010, and with their Portuguese manager back at the club he proclaims to love the most, we can expect more comings and goings ahead of the new season kicking off on Aug. 17.
But who will be arriving and who will bidding farewell to Stamford Bridge? This summer has already seen David Luiz linked with a move to Barcelona, via Daily Mail, while Edinson Cavani is rumored to be arriving for £53 million, as per The Guardian.
We gave warning of it in May, and now "silly season" is will and truly here in the Premier League. Sit tight as Bleacher Report keeps you up to date throughout the week with all the latest Chelsea news and gossip.
Last update: July 5
The Senegalese striker only joined the Blues from Newcastle United in January, but with six goals in 22 matches, Jose Mourinho evidently deems him surplus to requirements.
He may not be needed at Chelsea, but Ba remains a player in demand. Not only are Anzhi chasing his signture, the same report in The Mirror explains he has already turned down moves to West Bromwich Albion and former club West Ham United this summer.
Is John Mikel Obi going to reunited with former Blues teammate Didier Drogba at Galatasaray this summer?
Chelsea's Nigerian international has only recently finished up duties with the Super Eagles at the Confederations Cup, but while he was away in Brazil for the competition, he was being heavily linked with a move to the Turkish giants Galatasaray.
In June he was forced to deny quotes suggesting he would be swapping London for Istanbul (via The Independent) and now the Daily Mail is reporting he will be subject to a £16 million bid from the club.
Should the deal come off, it will end Mikel's seven-year stay in the Premier League after he joined Chelsea from Lyn Oslo in 2006.
Wayne Rooney is not leaving Manchester United this summer according to new Red Devils boss David Moyes.
At the back end of last season, Sir Alex Ferguson confirmed Rooney had told him he wanted to leave Old Trafford, kick-starting a frenzy of transfer rumors linking him with Chelsea and Arsenal (see Slide 9).
At his first official press conference as United boss on Friday (July 5), however, Moyes confirmed he will be retaining Rooney's services.
"Wayne Rooney is not for sale. He's a Manchester United player and will remain a Manchester United player. Wayne won't be sold by Manchester United," he told the gathered media.
"We are working together now. I have seen a glint in his eye, he looks happy and looks as if he is going to knuckle down."
Are Chelsea set to kiss goodbye to their chances of signing Cavani?
They've been chasing him all summer, but now the Daily Mail reports Chelsea are ready to give up on Edinson Cavani.
Paris Saint-Germain are rumored to have bid £43 million for the Napoli striker and according the Mail's report, Roman Abramovich is eager to avoid a bidding war for the Uruguayan.
Chelsea will now turn their attentions to cheaper alternatives Wayne Rooney and Robert Lewandowski as they bid to bolster their attack ahead of the new season.
Milan have been quick to deny the rumors, however, releasing a statement on the club's official website.
"There has been a meeting between Adriano Galliani, Stephan El Shaarawy and the young star's entourage," said the statement. "Everything went well. Stephan has always been an AC Milan fan and has reiterated his determination to continue playing for the Rossoneri.
"That pledge was reciprocated by Milan, with conviction. Milan and El Shaarawy will move forward together, as they have since 2011.
"No more talk of the transfer market, no more rumours."
That puts an end to that rumor then.
BBC Sport is reporting that Chelsea have held talks with Marco van Ginkel's current club Vitesse Arnham in a bid to bring the 20-year-old midfielder to Stamford Bridge.
Jose Mourinho met with the Dutch ace this week, with the youngster returning to Holland to discuss his future with his club.
One snag to the deal could be his hopes of featuring for Holland at the 2014 World Cup.
Van Ginkel is reportedly concerned that his first-team opportunities will be limited in West London, thus damaging his chances of going to Brazil next summer.
Eden Hazard is part of a growing Belgian contingent at Stamford Bridge
Chelsea may be chasing a host of star names this summer, but it seems they haven't neglected their youth policy with the pursuit of young Belgian Julien Ngoy.
He is currently not signed up to a club, either, so his capture will come relatively cheaper than the transfer fees Chelsea are used to paying for young stars.
Were he to join Chelsea, Ngoy would add to the club's growing Belgian contingent that currently features Eden Hazard, Romelu Lukaku, Kevin de Bruyne and Thibaut Courtois, who is on loan at Atletico Madrid.
The report also adds that Jose Mourinho has stated just five of his current Blues squad are guaranteed starters next season, with David Luiz and Juan Mata not believed to be part of that number.
Should Arsenal sign Torres, it could pave the way for Wayne Rooney to join Chelsea (see Slide 6).
Wayne Rooney's Manchester United future will become a little clearer this week as he prepares to sit down with new Red Devils boss David Moyes to discuss a potential transfer.
The Daily Mail is reporting that Chelsea and Arsenal are eagerly awaiting the outcome of those talks, but if Rooney is to leave United, both London clubs will have a fight on their hands to sign him.
The Mail's report adds that United will be looking for a fee of around £35 million for the player they signed from Everton in 2003, with Real Madrid and Paris Saint-Germain also interested.
This is a story that continues to rumble on with The Independent reporting of Chelsea's interest in early June, so expect more twists between now and the big kick-off in August.
For some, all the talk of big-money moves makes the summer an exciting part of the football calender, but not for Edinson Cavani it would seem.
The Napoli and Uruguay striker has been linked with Real Madrid (via The Guardian), Chelsea (via Daily Mail) and Manchester City (via BBC Sport) in recent weeks, but he has told Sky Sports that he would prefer not to have his name banded around the media.
"In this moment, everything is under pressure," he said ahead of Uruguay's third-place play-off with Italy in the Confederations Cup at the weekend. "Everything can be misunderstood. I prefer being calm. I go forward with my mentality.
"At the beginning of the Confederations Cup, I did not believe the market rumors would have given me trouble. But, at the end, I admit they have disturbed me a little."
