West Ham have agreed a fee with Bayern Munich for Moroccan full-back Noussair Mazraoui.
Sources say if the deal goes through, the Hammers will play an initial €16m (£13.47m) for the 26-year-old, with a potential further €3.5m (£2.95m) in add-ons.
Talks over personal terms are continuing for a player who has been linked with a number of clubs this summer, including Manchester United.
Mazraoui was born in the Netherlands and joined Ajax as a youngster.
He joined Bayern on a free transfer in 2022 and made 29 appearances for the Bundesliga giants in all competitions last season.
