Manchester City are in talks with Bournemouth over a deal to sign Nathan Ake when the transfer window reopens, according to The Athletic.
Pep Guardiola is desperate to strengthen his options at the back having lost Vincent Kompany last year and seen Liverpool run away with the title this season.
He also has concerns over John Stones and Nicolas Otamendi, while a serious injury to Aymeric Laporte coincided with a poor spell of form earlier in the campaign.
Guardiola is determined to revamp his central defence, with Ake emerging as a realistic target after being watched by City scouts for more than six months.
The Athletic claim Guardiola monitored the Dutchman prior to the January transfer window but is now ready to make a move, with early talks having already been held.
It is unclear whether the buy-back clause Chelsea inserted in the £20million deal which took him to the Vitality Stadium in 2017 is still active, although the Blues are likely to be the only competition City would face for his signature.
