As a result, some Stamford Bridge minds will undoubtedly already be turning to what can be improved in time for next season, where the West Londoners will once again look to challenge for top honours.
Ahead of this summer's transfer window, read on for all the latest rumours and speculation around Chelsea, with a special focus on the long-term futures of the club's on-loan assets.
Marek Hamsik, Napoli
For some years now, Marek Hamsik has been linked with a move away from the Stadio San Paolo, but the Slovakian has always resisted the allures of Europe's other giants.
That's not going to change anytime soon, either, with Napoli president Aurelio De Laurentiis claiming that his talisman isn't up for sale, per Radio KissKiss (h/t FourFourTwo):
It's only journalists who put him on the market. Marek has to come and tell me if he wants to go, but there is no more Neapolitan player than him. He has become Neapolitan and for me he is absolutely not for sale.
Of course if he came to me and asked to leave, then we'd have to discuss it.
Chelsea and Manchester United are mentioned as two of the sides supposedly interested in the creative maestro, and De Laurentiis comes across as sincere in admitting that he wouldn't stand in the way of Hamsik's desires.
BeIN Sport's Matteo Bonetti and writer Nik Postinger feel that Hamsik has a habit of shrinking in the biggest fixtures, however:
However, to see a president speak so loyally of one player is a rare trait, and Hamsik may see that as more valuable to his career than any potential big-money move.
Oriol Romeu, On Loan at Valencia
After spending the 2013-14 season on loan with Valencia, Oriol Romeu has admitted that he could complete a permanent move to Spain, but only if his parent club permits it.
I'm very happy here. The latest we know is that Valencia are happy with me and they would like me to stay. I'm very comfortable here, but we'll have to wait until the end of the season.
I still have a year on my contract and anything can happen. It's up to Chelsea to decide.
Romeu's official Chelsea profile shows that the holding midfielder has made a total of 33 appearances for the English club since completing a 2011 switch from Barcelona.
WhoScored.com picked the anchor out as man of the match for his Europa League performance against Swansea City earlier in the season:
However, the 22-year-old would appear to be enjoying the regular first-team football that many at Stamford Bridge have found difficult to come by, and he may not be on the Blues' books for much longer.
Romelu Lukaku will only extend his stay at Goodison Park if Everton succeed in their bid to qualify for next season's Champions League.
That's the belief of club legend Graeme Sharp, who made more than 300 appearances for the Toffees, per the Daily Star's Carl Eldridge:
The Lukaku situation will take care of itself. He has said he wants to play in the Champions League. Now, if Everton don’t get that fourth spot, that answers its own question.
If Everton get a result—by that I mean a victory and three points against Manchester United—they will still believe there’s an outside possibility of fourth spot. It’s got all the makings of a fantastic game.
Sharp was speaking prior to Sunday's fixture against the Red Devils, with Roberto Martinez's men sitting two places and nine points above United in fifth and having the chance to again apply pressure on fourth-place Arsenal.
Oliver Kay of The Times even goes as far as to claim Lukaku is the best striker among Chelsea's ranks, pointing out Jose Mourinho's mistake in farming him out:
Lukaku's loan at Everton has been a highly productive one. The Belgian international has scored 13 goals and registered eight assists in 25 league starts, per Transfermarkt, leaving Martinez with a void to fill should he be unable to make the deal permanent.
