Manchester City are close to finalising a deal for Monaco left-back Benjamin Mendy, Sky sources understand.
Monaco value the player at more than £50m and are not willing to sell unless they receive an "exceptional offer".
City are thought to have been offering nearer to £40m but need to make progress on signing a left-sided defender following the departures of Gael Clichy and Pablo Zabaleta.
Sky Sports News HQ understands significant progress has been made in negotiations between the clubs in the last 24 hours and the deal could be agreed before the end of the week.
Mendy is keen on a move to the Premier League and earlier this week, posted a picture on Instagram wearing Union Jack shorts with the caption: "See You Soon".
The France international helped Monaco win the Ligue 1 title last season, making 39 appearances as Leonardo Jardim's side also reached the semi-finals of the Champions League.
Monaco appear to have already found Mendy's replacement, following the signing of Feyenoord's Terence Kongolo for £12m.
