Bournemouth centre-back Nathan Ake is on the verge of joining Manchester City.Reports broke today that the Cherries had accepted a £41m bid from Pep Guardiola's side for the Dutch defender.Chelsea did have a buy-back clause inserted into the deal when they sold Ake, but Frank Lampard's side decided against re-signing him leaving the path clear for City.The 25-year-old was one of Bournemouth's bright sparks in an otherwise dismal 2019/20 campaign which saw the south coast side relegated from the Premier League.However, their chances of promotion from the Championship in 2020/21 will be seriously strengthened by the financial injection from the sale of Ake to City.

Amazingly, the Dutch international will be the 10th most expensive centre-back of all time, overtaking the £40.5m City coughed up for Eliaquim Mangala in 2014.

Guardiola's side love spending big on defenders, don't they?

Below, we've provided the 20 most expensive centre-backs in football history and for context, we've included the deal for Ake at number 10.

Man City crop up on five occasions in the top 20, with United also contributing with three deals of their own.

Juventus and Paris Saint-Germain are the other two teams to feature on more than one occasion with two apiece in the top 20.

From a selling perspective, Valencia, FC Porto and Ajax are the only three clubs to feature twice and they've all recouped some enormous fees over the past few years.

The transfer market has gone a bit bonkers of late and with a premium on centre-backs, it seems only a formality that we will soon see the first £100m+ deal for a central defender.
