Maresca is also understood to be angry at suggestions that he fell out with the club's medical staff, and subsequently risked the health of first-team stars such as Cole Palmer and Reece James. He was frustrated with the amount of confrontations he was forced to have with the club's power-brokers, especially when it came to team selections and potential substitutions.
Regardless, he has been tipped to make a swift return to the dugout by Premier League legend Alan Shearer.
He said: "His time at Chelsea should be viewed as a successful spell for Maresca. They beat the best team around last year in PSG; he out-coached the Coach of the Year. They won the Conference League, which you’d expect, but not many thought they’d go to the Club World Cup and win.
"He’s in and around the top four, so for me, he’s done a really good job. He’ll leave with his stock high. I don’t think he’ll struggle to get another job because of the work he’s done at Chelsea and Leicester. Whether he gets one of the big ones remains to be seen. There’s been talk about City, hasn’t there, but it depends on if Pep Guardiola decides to leave and when, but he won’t struggle for a job in England or abroad."
He added: "You know when you go into that job what you're doing, it's a very different football club to others in terms of how it's managed. That's not Maresca, that's the people above him. Their model is obviously to buy young, develop them, and give them crazy long contracts with the potential to sell. I don't think you're going to win the league like that. You might get into the top four because you can spend, but in the main, the guy coming in has to do better than the guy that's just left."
