Brentford boss Thomas Frank has signed a new contract with the club that runs until the end of the 2024-25 season.
Frank led the Bees to promotion to the Premier League last season as they ended a 74-year exile from the top flight.
His assistant Brian Riemer has also signed a new contract until 2025.
"They have been integral to the success that we've shared over recent seasons," said Brentford director of football Phil Giles.
"We want to continue to take Brentford forward, to compete with clubs far bigger than us, and to see how far we can progress.
