Maresca stunned even members of his own staff when – after beating Everton 2-0 for Chelsea’s solitary Premier League win in December – he said “many people” had made it his “worst 48 hours” since joining the club.
Those comments came without any warning to club staff or senior management, who would have preferred any discussions to remain private.
But friction had been brewing in the months before that.
Maresca had hoped to raise his profile following the Blues’ successes through opportunities outside the club. He was planning to publish a book before being blocked, and spoke at Il Festival dello Sport – an event in Italy organised by La Gazzetta dello Sport newspaper – without the club’s permission.
He also made public that he disagreed with the club not signing a central defender after Levi Colwill injured his anterior cruciate ligament in pre-season. The club’s hierarchy explained that doing so could prompt academy prospect Josh Acheampong to request a transfer, which ultimately led Maresca to back down.
The former Leicester manager has also switched agents – from the Wasserman agency to Jorge Mendes – and has been talked of as a potential successor to Pep Guardiola at Manchester City, which Maresca has dismissed.
In addition, he has increasingly avoided wearing club tracksuits – opting instead for his own clothing.
Following his last game with Chelsea – a 2-2 draw with Bournemouth on 30 December – assistant manager Willy Caballero said Maresca felt too unwell to do his post-match media duties, but it is understood his absence was more due to his disillusionment at the club.
And it was noticeable that when Chelsea posted a 52-second video on social media on New Year’s Eve summarising their year, there was no trace of Maresca.
