AS Monaco are understood to have paid around €30m (£27.8m) for Keita, who had rejected a number of other clubs during the current transfer window.

The 22-year-old has put pen to paper on a contract which will keep him at the Stade Louis II until 2022, becoming the club’s 10th new arrival of the summer and second signing of the day after Stevan Jovetic.

Keita’s arrival could pave the way for Kylian Mbappe to join Paris Saint-Germain, while Thomas Lemar has also been linked with an exit amid interest from Liverpool and Arsenal.
