Joleon Lescott is more confident that Nathan Ake would prove his worth at Manchester City than he is Kalidou Koulibaly.
The Blues are close to making Ake their second major signing of the summer after Ferran Torres's move was officially confirmed on Tuesday evening, with the club having agreed a £41m deal with Bournemouth.
That is not expected to be the end of their strengthening of the defence this summer though. With Pep Guardiola seeking another centre-back after the club failed to replace Vincent Kompany last year, Napoli's Koulibaly remains of interest.
Lescott knows the standard of defence needed to win a Premier League title, having been an important member of Roberto Mancini's 2011/12 squad and also featuring in the side that won the league two years later under Manuel Pellegrini.
While the signing of Ake appeals, he is less convinced that splashing out on Koulibaly would be worth it.
"I think Nathan Ake would be a very good signing for Manchester City if he does sign. He’s an established Premier League defender and while Bournemouth were relegated, Ake has proven to be more than capable at this level," Lescott told the Football Index Podcast.
"He probably didn’t perform as well this season as he would have liked, but he rarely has a bad game and his decision making is excellent. He loves to defend and he is comfortable on the ball so I could see him settling in well at Manchester City.
"I’m not convinced that Koulibaly would be the right signing for Manchester City and I think the club is going down the right route with Ake. Koulibaly is a few years older than Ake and would cost twice as much, while he’d also need time to adapt to the Premier League. There’s no guarantee that Koulibaly could perform in the Premier League as he has done in the Serie A, which is a completely different proposition."
Pick your City player of the season
The arrival of Ake will further limit opportunities for John Stones even if Koulibaly does not join.
Stones has struggled with form and fitness for at least the past 18 months and youngster Eric Garcia has been the preferred partner for Aymeric Laporte since the squad returned to training in May.
With the England centre-back's future up in the air, Lescott thinks it is a shame the player has not been able to reach his potential despite the trophies he has picked up at the Etihad.
"John Stones has arguably not lived up to what expectations were for him when he signed for Manchester City," he added. "I think he does get a rough time because he has performed and no-one can ever take away from him what he has achieved at the club, but he hasn’t reached the potential many thought he had at the time.
"I think injuries have played their part and it was unfortunate he was never able to learn from Kompany as that would have made the world of difference to any young central defender."
