Just over a week ago, the Blues reached a mutual decision with Mauricio Pochettino for the head coach to depart his role at Stamford Bridge.
However, Chelsea's co-owners Todd Boehly and Clearlake Capital, as well as co-sporting directors Paul Winstanley and Laurence Stewart, have wasted no time in moving for an alternative.
Several days of negotiations are expected to conclude with Leicester City boss Maresca penning a contract of at least five years before the end of the week.
The club's hierarchy are said to feel that they have secured the ideal candidate to fit into their desired business model and to deploy their preferred style of play, which is possession-based football.
Maresca transfer influence to be limited
Despite reportedly being wholeheartedly impressed with what Maresca can offer Chelsea, it appears that there will be some restrictions placed on the 44-year-old.
According to reporter Nick Purewal of the Evening Standard, Maresca will not have control over which players will arrive at Chelsea during the summer transfer window.
Instead, his input will be taken on board in the hope that the relevant parts of Chelsea's structure can cooperate in order to deliver success on the pitch.
The report adds that Chelsea are currently in the market to strengthen four positions in their squad, with some names having been specifically placed on their shortlist.
Osimhen spearheads Chelsea transfer wishes
Chelsea are said to want to acquire the services of a new goalkeeper, centre-back, left-back and centre-forward ahead of the new season.
Despite their well-documented issues with the Premier League's Profit and Sustainability regulations, as well as UEFA's, Napoli forward Victor Osimhen remains their priority target for the attack.
Meanwhile, as per reports elsewhere, Burnley goalkeeper James Trafford and Fulham defender Tosin Adarabioyo could also move to the club, the latter being available on a free transfer.
With regards to a left-back, Marc Cucurella excelled during the final weeks of Pochettino's reign, with Ben Chilwell potentially facing a fight for his future.
Djordje Petrovic is another to impress, the goalkeeper having proven value for money since arriving from New England Revolution, but the current perception is that Maresca would prefer to upgrade to a stopper who is better with the ball at his feet in order to start attacks.
