Marinus Dijkhuizen has been sacked as Brentford's head coach after just eight league games and replaced as head coach by Lee Carsley, until the end of the season.
The Bees have made a poor start in the Championship and sit just above the relegation zone, although they have a game in hand against Birmingham.
Getwestlondon understands the players were unhappy with assistant Roy Hendriksen's training methods and owner Matthew Benham has decided to make a change.
A club statement read: "Brentford Football Club can confirm that the club, head coach Marinus Dijkhuizen and his assistant, Roy Hendriksen, have parted company.
"The club would like to put on record its thanks to Marinus and Roy for all their efforts during their time at Griffin Park.
"Lee Carsley has been promoted to Head Coach until the end of the season when the position will be reviewed.
"Lee has vast experience of the English game and has hugely impressed with his work with the Club's Development Squad. He will be assisted by Paul Williams.
"The club believes Lee deserves the opportunity to step up and help shape Brentford FC's future on the pitch.
"Chairman Cliff Crown will update supporters via the Brentford FC website this afternoon."
It is the shortest reign of any permanent appointment made by the club in their history, breaking Eddie May's record of 20 games. Nicky Forster, who was in caretaker charge in 2011 got more games in charge.
