While this may not immediately trigger a managerial change, the club's top brass might already be contemplating potential replacements for Maresca. Chelsea could take several paths - they could hire a currently employed manager or offer the position to someone who is currently without a club.
So, who might be in the running if Chelsea decide to part ways with Maresca?
Zinedine Zidane
A serial winner, Zinedine Zidane has been unemployed since leaving Real Madrid for the second time in 2021. However, that hasn't stopped him from being linked with other roles; both Manchester United and the French national team have reportedly considered him in the past.
There's no question that Zidane would bring a wealth of experience to West London. His trophy cabinet includes three Champions League titles, two league titles, and numerous other accolades.
Whether Zidane would be interested in a move to West London is yet to be seen, but his appointment would undoubtedly be a significant coup for Chelsea.
Gareth Southgate
Gareth Southgate, who has been unemployed since stepping down as England manager, has consistently emphasised that he's not actively seeking new employment. However, the resources available to him as Chelsea boss could be too enticing to resist.
It's worth noting that Southgate hasn't managed in the Premier League for nearly two decades, with his last stint at Middlesbrough ending in 2009.
Liam Rosenior
Todd Boehly could potentially leverage his football connections to secure one of the most promising young managers in world football, should he choose to do so. Liam Rosenior made a name for himself in early roles at Derby County and Hull City before taking the helm at French side Strasbourg in 2024.
His career trajectory has continued to ascend, guiding them to a seventh-place finish last season. Although Rosenior signed a new contract earlier this year, his employment by BlueCo means any move for him would be relatively straightforward.
Frank Lampard
The idea of Frank Lampard returning to Stamford Bridge may seem laughable to some, but it's not unprecedented. The legendary former midfielder has already had two managerial stints at Stamford Bridge.
Lampard has certainly managed to restore his reputation since then. He's got Coventry City soaring at the top of the Championship, and it seems likely that the Sky Blues will secure a place in the Premier League.
Regardless of what happens, Lampard looks set to be back at Stamford Bridge next season, with Chelsea or Coventry.
Brendan Rodgers
Brendan Rodgers, who also has ties to West London, began his successful career within the Chelsea academy. After climbing through the ranks, he had notable stints with Swansea, Liverpool and Leicester, winning the FA Cup with the latter.
His two trophy-filled tenures with Celtic could make him an attractive prospect for Chelsea. Currently without a job after leaving Celtic under a cloud, Rodgers is available.
Erik ten Hag
A somewhat unexpected choice, Erik ten Hag was dismissed by Manchester United last season despite having won the League Cup and FA Cup during his time with the Red Devils. His tenure with German side Bayer Leverkusen ended in strange circumstances, as he was let go after just two league matches.
This might deter Chelsea, but as a cost-effective option with the potential for silverware, Ten Hag could emerge as a contender for the Blues.
