Holland worldwide Ake enjoyed his time on loan with the Cherries last season and proved he had what it takes to be a Premier League footballer, so much so that Chelsea took him back to Stamford Bridge early where he was a regular in their first-team squad.
Given John Terry's eventual departure and the return of some very promising players back from loan spells, it seems unlikely that Ake is going to get a look into the first team at Stamford Bridge.
While he had to wait until November for his first league start under Eddie Howe last season, the Netherlands global quickly snatched a first-team role, making 12 appearances for the club and scoring some important goals along the way, including late winners against Stoke City and Liverpool.
Bournemouth are reportedly closing in on a club-record £20m deal to sign Nathan Ake from Chelsea following his successful loan spell at Dean Court last season.
He told the club's website: 'It's an exciting challenge. "With the help of the manager here, I know I can keep improving and become a better player", Ake said.
The Burkina Faso global signed for Les Gones on an £8m deal after impressive loan spells at Vitesse Arnhem and Ajax Amsterdam.
"Nathan is an outstanding young player with a fantastic attitude and a great desire to learn and develop".
The Guardian is reporting that the Netherlands defender is on the verge of completing a permanent move to the club he spent the first half on loan to last season.
