Arsenal are on the brink of signing William Saliba from Saint-Etienne.
Football.london says talks between the two clubs have reached an advanced stage.
The 18-year-old will arrive at the Emirates and then be loaned back to the Ligue 1 club for next season.
The Gunners are expected to pay £26m for the Frenchman.
Saliba marks the second signing of the summer for Unai Emery following the arrival of Gabriel Martinelli.
