Mark Warburton has been named as the new manager of League One side Brentford.
Following Uwe Rosler's departure to Wigan, Jimmy Floyd Hasselbaink and Michael Appleton were linked with the vacant post at Griffin Park, but Brentford have decided to appoint from within.
Warburton, a former Watford youth coach, was linked with West Bromwich Albion last season as the Premier League club looked for a new sporting director.
He has been at the club since Feburary 2011, working alongside the then caretaker manager Nicky Forster and he became sporting director in 2012.
Chairman Cliff Brown said: "We have done very well this season with a squad Mark has helped to assemble and with the existing coaching and back room staff.
"We believe Mark will offer continuity at a key time and enable us to build on the past two-and-a-half years.
"Mark's coaching credentials are without question, he is highly qualified to deal with both professionals and our young players.
"Mark has a commitment to blooding young players into the first team and to the academy and that remains important for the club's development.
"Mark has done an exceptional job as sporting director since taking that role 30 months ago and we are happy he can step into this new role seamlessly.
"We believe it will help the players and staff to work with someone they know and respect and we look forward to continuing success for Brentford Football Club."
Warburton inherits a squad that are fourth in Sky Bet League One, six points off the automatic promotion places.
