Manchester City remain interested in bolstering their defensive ranks with the signing of Kalidou Koulibaly - despite Lionel Messi emerging as their top target.

Pep Guardiola has prioritised his defence in the summer transfer window after missing out on the Premier League title and suffering Champions League heartbreak last season.

Nathan Ake has already arrived from Bournemouth, while the Etihad club have been in a tussle with fierce rivals Manchester United to land Koulibaly from Napoli. 

But after Messi dropped a huge bombshell this week demanding to leave Barcelona, City were expected to drop other targets to bring in the Argentina superstar. 

And City, it is claimed, are understood to be willing to meet the lower price tag once bonuses are included.
