Gusto, 23, joined Chelsea from Lyon in January 2023 and has made 134 competitive appearances for the club, contributing three goals and 17 assists. Last season he recorded two goals and three assists across 34 Premier League matches.
Maresca's arrival at Manchester City as Pep Guardiola's replacement is the key factor behind Gusto's interest in the move, having previously worked under the Italian manager. Gusto is also part of France's World Cup squad.
The obstacle to the transfer is now between the clubs. Gusto is contracted at Stamford Bridge until 2030, meaning City will need to agree a fee with Chelsea to complete the move.
Whether Chelsea are willing to sell a player who has established himself as a reliable performer in the Premier League will depend on their own recruitment priorities and whether an acceptable offer is forthcoming. The player's own position — having already indicated he is open to the switch — gives City a clear starting point for their negotiations.
City's need for a right-back has become more apparent as they reshape the squad under Maresca. The arrival of a player who already has a relationship with the new manager, combined with Premier League experience and established quality at the position, makes Gusto an appealing target beyond just filling a vacancy.
For Chelsea, the decision is complicated by the fact that Gusto has been one of their more reliable performers and losing him would require investment in a replacement. The club's own defensive business — having already sold Marc Cucurella — means they may be reluctant to deplete the position further without a suitable option already in place.
