Manchester City have agreed a deal in the region of ?17m to sign defender Manuel Akanji from Borussia Dortmund.
The deal is made up of an initial ?15m payment plus ?1.7m in add-ons, and Akanji is already in the UK and ready to undergo a medical with City.
Switzerland international Akanji had entered the final year of his contract at Dortmund and had yet to make an appearance for the Bundesliga club this season.
City boss Pep Guardiola refused to rule out making more signings before Thursday’s transfer deadline in his press conference ahead of Wednesday’s Premier League game against Nottingham Forest.
Asked about any further transfer business, Guardiola said: “I don’t know, I don’t know what will happen.”
