Following Wednesday's second-leg defeat to Paris Saint-Germain in the Champions League, questions have been raised about the quality and capability of Chelsea's squad at the top level.
Defeat sent the Blues out of Europe's elite competition, further compounding what has been an awful season.
With only the FA Cup left to play for, we take a look at who should stay at Stamford Bridge to spark a revival next campaign.

The 6'6" Belgian shot-stopper is one of many whose form has slumped since Chelsea's title-winning season, with a three-month injury perhaps to blame for his inconsistency of late.
However, at 23-years-old, Courtois is still incredibly young and has a lot of time to reach his extraordinary potential. Pulling the trigger after one bad season would be hasty.
Chelsea's Mr Consistent. The Spaniard has been rotated between right and left-back all season yet never failed to deliver. He's become a vital component of the Blues' back four.
One of the club's most experienced players whose form has fallen off a cliff this season, Ivanovic has endured nightmare after nightmare at right-back.
The Serbian's recent performances in the middle have been more encouraging, though, and although he shouldn't be a starter for Chelsea, his presence is vital in the dressing room.
One of few players remaining from 2012's Champions League winning team, Cahill has won everything there is to win with Chelsea.
Unfortunately for the Englishman, the emergence of Kurt Zouma has seen his place as a starter lost, whilst his performances have left a lot to be desired.
Few players can look back at this season with any sort of pride - however, prior his season-ending injury, Zouma played with quality and passion and whilst he still has a lot to learn, time is well and truly on his side.
The 35-year-old is still Chelsea's best defender and the only remaining member of their once formidable and experienced spine. He simply must stay.
A nightmare signing by the Chelsea board. When he was bought for over £20 million last summer, Rahman was expected to be the club's left-back for years to come.
However, the 21-year-old has failed to convince that he's the new Ashley Cole and with Kenedy often asked to play out of position ahead of him, his future at Chelsea looks bleak.
Jon Obi Mikel
A man revitalised under Hiddink, Mikel has become one of the first names on the teamsheet. The Nigerian is unspectacular but reliable, and a good option to have at the club.
The Serbian has been awful this season - you can count the number of good games he has had on one hand.
With his confidence shot to pieces and no obvious way of solving the problem, it could be best for both parties to go their separate ways.
Fabregas has found some form again under Hiddink. His relationship with Costa appears reinvigorated and has played a huge part in Chelsea's improved league form.
Does he do it against the best sides often enough? Probably not, but he's a useful player to have with an eye for a pass like no other at Stamford Bridge.
It's incredible to think that Juan Mata and Kevin De Bruyne were considered inferior to Oscar upon Mourinho's first season back in charge.
Had he progressed the way Chelsea fans expected him to, perhaps a stay would be deserved, but the fact of the matter is he hasn't improved since arriving in 2012.
Simply put, the Brazilian has been Chelsea's best player this season. His free-kicks alone should see him remain at Stamford Bridge this summer.
The Spaniard has failed to make the impact Chelsea fans hoped he would since joining from Barcelona last summer.
His form has improved recently, but Pedro still looks a little bit too lightweight for the Premier League. Time must still be given.
Verdict: Stay (until January at least)
It's quite a mystery how someone so crucial to last season's title winners can perform so poorly the next.
Without a Premier League goal all season, it seems Chelsea fans have lost patience with Hazard's lack of product and effort. The Blues must accept any bid in the region of £50 million for him.
Will he stay? That remains to be seen, but Chelsea should certainly want him to stay.
When on song, the Spaniard is a deadly and powerful striker capable of both the beautiful and the ugly. The Blues must build their team around him.
With regards to youngsters, Ruben Loftus-Cheek, Kenedy and Bertrand Traore have all performed well when called upon and are the future of Chelsea Football Club.
Loic Remy and Radamel Falcao, on the other hand, must go, whilst Alexandre Pato and Matt Miazga are yet to show fans what they're capable of.
