Arsenal’s head of coach and player development, Marcel Lucassen, is to leave the club, The Athletic have revealed.
The Dutchman, who has been at the club since 2018, has resigned due to 'personal family reasons'.
Per Mertesacker was instrumental in bringing Lucassen in two years ago, having worked with him with the German national team.

Lucassen’s responsibilities will be taken on by Luke Hobbs as Head of Academy Coaching. This will cover recruitment and development.
Hobbs knows the club well, having taken charge of Football Operations at the Hale End Academy in 2013 before becoming interim Academy manager in 2017.
