Chelsea need a superb display next season to vanquish the memories of this campaign.
Antonio Conte's arrival will bring about a new regime, and the tactician will want total commitment from each and every player in the squad.
The club will make some significant changes and hope to sign some world-class professionals, but questions still remain about the future of a number of players at Stamford Bridge.

In almost every area of the pitch, Chelsea need to evaluate their current squad.
The future of some first-team stars is particularly uncertain because the Blues will not be playing European football next term.
Thibaut Courtois is thought be contemplating a move away amidst reports of a fall-out with goalkeeping coach Christophe Lollichon. According to the Daily Mirror, interim boss Guus Hiddink admitted there had been a disagreement between the pair, but insisted the shot-stopper is happy and is not planning to leave the club, with Real Madrid, Barcelona, and Paris Saint-Germain all monitoring the situation.
Conte needs the issue sorted soon, and he does have Asmir Begovic as a deputy to Courtois. The former Stoke City goalkeeper has had a decent season, stepping in when Courtois was out through suspension and knee injury. Begovic will be given ample opportunity to prove himself in pre-season.
Club veteran John Terry is set to depart as a free agent after 21 years at the club, but in contrast, Gary Cahill has made some commendable performances that should see him stay.
Frenchman Kurt Zouma is undergoing a rehabilitation program on his right knee, an injury that has sidelined him from the upcoming Euros in his homeland. However, he should still be in Chelsea's long-term plans.
Meanwhile, Cesar Azpilicueta’s future is secure as despite dismal showings from the team, the Spaniard cannot be solely blamed for some horrendous displays at the back.
Branislav Ivanovic earned a new one-year deal in January, which baffled some fans, and Conte may call time on the Serbian's career, as he has lost his pace and buying a younger option seems more viable in his option.
Youngsters Matt Miazga, Baba Rahman and Michael Hector shouldn’t expect to feature in many of the league games, but could get their chance in cup games.
Chelsea haven't been at their best because of a lack of quality in midfield.
Cesc Fabregas has given a glimpse of his previous form in recent outings, but he has struggled for much of this season. Yet, under Conte, he could return to his former glory and play a vital role.
Oscar and Eden Hazard have not been at their best either, but Hazard has redeemed himself with some stellar performances, particularly against Chelsea. The former, though, could be a part of this summer's exodus.
John Obi Mikel and Nemanja Matic might also be in their final season at the club, with nothing noteworthy about their performances all year.
Willian, on the other hand, has been one of the only silver linings in the Blues’ campaign, scoring 11 goals alongside ten assists, and can be a pivotal part of Conte's plans.
Ruben Loftus-Cheek, Kenedy and Lucas Piazon need to stay patient for their opportunities.
Diego Costa has had to shoulder much of the team's goal-scoring responsibilities with Radamel Falcao and Loic Remy failing to prove their worth.
Costa will remain their main striker under Conte, while the latter two will leave following a lacklustre season.
Alexandre Pato could stay put as Conte is familiar with his credentials from the forward's time at AC Milan, though he would want to use him chiefly as a backup for Costa. And Pedro will have to put in some big performances if he has any chance of success at the west London club.
Pre-season could be crucial in determining all of their fates.
