Edimilson Fernandes has joined German Bundesliga club 1. FSV Mainz on a permanent transfer for an undisclosed fee.
The Switzerland midfielder departs West Ham United after three years in east London, having joined the Hammers from Sion in August 2016.
Fernandes totalled 48 first-team appearances across his first two seasons at London Stadium, scoring a solitary goal in an EFL Cup win over Chelsea in October 2016.
The 23-year-old spent the 2018/19 campaign on loan at Italian Serie A club Fiorentina.
West Ham United would like to thank Edimilson for his service and wish him every success for his future career.
