The Netherlands international follows Spanish winger Ferran Torres to the Etihad Stadium as Pep Guardiola looks to refresh his squad.
Manchester City have completed the signing of Bournemouth defender Nathan Ake in a deal worth an initial £40 million ($53m).
Ake has signed a five-year deal and becomes Pep Guardiola’s second major signing of the summer following the £21m ($27m) capture of Valencia winger Ferran Torres.
The deal represents a club-record transfer fee for Bournemouth, who could receive a further £1m ($1.3m) in add-ons for the Netherlands international.
Goal reported last week that the two clubs had agreed terms, and the 25-year-old has since returned from an end-of-season break to complete his medical and sign his new contract in Manchester.
Ake started his career at Chelsea, and the west London club did have a buy-back option, but it is understood that they were put off by the fee despite Frank Lampard considering him as a viable option.
City have been in the hunt for a new central defender since the exit of captain Vincent Kompany in June 2019. They were interested in Harry Maguire but balked at the asking price for the England international, who eventually joined Manchester United in an £80m ($97m) deal last year.
Despite Bournemouth’s relegation to the Championship, Ake’s reputation has soared since he left Stamford Bridge in 2017. As well as being a homegrown player, he has experience of playing regularly in a back-three and can also provide cover at left-back.
Without Kompany last season, City’s defensive options were stretched when Aymeric Laporte missed five months of the campaign with a knee injury.
Academy product Eric Garcia has emerged as Laporte’s most trusted partner in the centre of defence, but Barcelona are keen to take their former youth team player back to the Camp Nou.
John Stones and Nicolas Otamendi also face an uncertain future after their form dipped this season and could be potentially offloaded in the transfer window.
Ake may not be the only defensive signing City make this summer, with the club also looking at Napoli’s Kalidou Koulibaly and Sevilla’s Diego Carlos as they try to close the gap on Liverpool having failed to mount a Premier League title challenge in 2019-20.
Along with Torres, City have already completed deals for Juventus forward Pablo Moreno, Brazilian full-back Yan Couto from Coritiba and Burkina Faso defender Issa Kabore from Mechelen.
