Ake has put pen to paper on a five-year deal, keeping him at City until the summer of 2025.
The 25-year-old's footballing journey began at VV Wilhelmus at the age of six, but he moved to ADO Den Haag after two years, before signing for Feyenoord at the age of 12.
He joined Chelsea aged 16 in 2011 and was a key part of their 2012 FA Youth Cup winning side and then captained their U21s to the 2013/14 U21 Premier League title.
Though he made his senior bow as a second-half sub against Norwich on Boxing Day 2012 his chances at Chelsea were limited and he went in search of regular first-team football.
He spent a month on loan at Championship side Reading in 2015, making five appearances, before spending the 2015/16 season on loan at Watford, making 28 appearances for the Premier League side.
Bournemouth offered him a six-month loan the following campaign. He played 12 times and scored three goals for the Cherries, returning to Chelsea for the second half of the campaign and making five appearances.
Bournemouth made the move permanent that summer, signing Ake for £20 million and he became a key player for the south coast side, making 109 appearances after joining permanently, scoring eight goals.
He has since won 13 senior caps for Holland, scoring two goals, having made his debut in a 2-1 win over Morocco in May 2017.
