According to Le Parisien, no formal agreement has yet been signed, but discussions between the two parties are described as well advanced and could be finalised within the next few days.
Chabot, who hails from the Vendée region, has been repeatedly fast-tracked to train with Angers' Under-19 side and reserve team despite his age, an indication of the regard in which he is held within the club's academy set-up. His decision to reject the professional terms on offer reflects a determination to test himself at a higher level, with Manchester City's global scouting network having identified him as one of the most promising young goalkeepers to emerge from French football in recent years.
The teenager's talent has already been recognised on the international stage. He was called up by France for last autumn's Under-17 World Cup, further evidence of a rapid rise through the age groups that has made him a target for one of European football's biggest clubs.
Barring any last-minute setback, Chabot is expected to continue his development in England, joining the ranks of young talents City have recruited from across Europe in recent years as part of their long-term academy strategy, which has increasingly focused on identifying prospects at academy level before they sign their first senior contracts elsewhere.
The move continues a familiar pattern for English clubs targeting promising French prospects before they commit to their first professional deals, a trend that has accelerated in recent transfer windows as clubs look to secure young talent on favourable terms.
Angers, for their part, will lose a goalkeeper regarded as one of the most promising to emerge from their academy in recent seasons, a departure that will sting given how close he had come to signing his first professional contract with the club that developed him.
