The Blues have made a move for Sterling a top priority this summer with Thomas Tuchel eager for the club to sign the England international.
The German boss wants to add more firepower to his side this summer but defence is also an area of concern following the departures of Antonio Rudiger and Andreas Christensen.
According to the Daily Telegraph, Chelsea have now turned to their former defender Ake as part of their summer rebuild.
Ake made his Chelsea debut back in 2012 and made 17 senior appearances for the club. In 2017, he joined Bournemouth in a £20million deal having impressed on loan the previous season.
Following Bournemouth’s relegation to the Championship in 2020, he joined City in a deal worth £40million.
According to the Telegraph, Chelsea co-owner Todd Boehly contacted City on Monday to discuss their valuation of both Sterling and Ake with the Blues keen to sign both players.
Tuchel previously tried to sign Ake while he was in charge of Borussia Dortmund with the 27-year-old open to the idea of returning to London.
Chelsea have enquired into Matthijs de Ligt’s availability but Juventus are holding out for at least £60m – and also want Timo Werner as part of the deal.
Ake has won two Premier League titles and a League Cup in his two years in Manchester but started just 10 league matches last season, with a further eight starts coming in cup competitions.
