Donnarumma, 26, has penned a five-year deal at the Etihad for a reported fee of £26 million ($35 million).

Donnarumma, who will wear the 99 shirt, was an integral part of the PSG team that won the Champions League last season, and was in goal for Italy when they won Euro 2020.

"To have signed for Manchester City is such a special and proud moment for me," said Donnarumma, whose signing was announced a day after the summer transfer window closed.

"I am joining a squad packed with world-class talent and a team led by one of the greatest managers in the history of football in Pep Guardiola. This is a club every player in world football would love to join."

Donnarumma, who stands 1.96 metres (six feet, five inches) tall, started his career at AC Milan, where he made his debut as a 16-year-old, before signing for PSG in 2021.

He has made 412 club appearances and won 74 international caps.

City's director of football Hugo Viana said Donnarumma's arrival was a huge boost for the club, who have started the season poorly.

"Gianluigi's pedigree, quality and record speaks for itself, and we are all absolutely thrilled he has joined us here at City," he said.
