"The board, with Matthew’s approval, has made the decision that the trio will leave Brentford at the end of the 2014/15 season." a statement on the club's website read.
"Mark and David will continue to work with the first-team on a day-to-day basis through to the end of the season – with the support and backing of Matthew and the Club’s Board – as Brentford push for promotion to the Premier League."
The statement confirmed that club officials and the management team had been in discussions about the 'club's future' for several weeks.
The club will at the end of the season restructure the management of the team to accomadate a Head Coach rather than a manager and a new Sporting Director. Alongside changes to the club's scouting networks, the club also said their new Head Coach would be 'heavily involved' in recruiting players but would not have 'absolute veto'.
“Some of the decisions taken to date have been easy and some, like this one, have been extremely hard."
Mark Warburton said: “I will be forever grateful to Matthew for giving me the opportunity to be Manager of this fantastic Football Club and for what he has done for the Club since I have been here."
“It has been an absolute honour and a privilege to do the job and I have had the pleasure of working with a fantastic group of players and staff and have enjoyed the backing of a magnificent set of supporters."
“While I am disappointed that we have been unable to reconcile some key philosophical differences, I’m relieved we now have clarity."
