Rasmus Ankersen has been named co-football director at Brentford.
Ankersen was the chairman of Danish league leaders FC Midtyjlland.
Mark Warburton is leaving his post as manager of the Bees, despite having led them to the play-off semi-finals in their first year in the Championship, as the club puts a new structure in place.
Brentford chairman Matthew Benham said: "When changes to the football department were first announced, we were very clear that we wanted Brentford to be a club that could reach the Premier League and stay there.
"We believe this can only be achieved sustainably with an innovative approach to player recruitment and the overall management of the club. Rasmus and Phil can help us achieve our aim.
"The director of football role is a big one and splitting it means we can add the expertise of both of them to our management structure."
