Manager Thomas Frank has signed a new contract at Brentford, keeping him at the club until summer 2027.
The Dane had only put pen to paper on a three-and-a-half-year extension in January, but the club have reaffirmed their commitment to him with fresh terms.
Frank, 49, was appointed in October 2018 and has led the side into the Premier League, where they - at the time of writing - currently lie in the top half.
He said: 'Being a head coach at a club is like a relationship; there are highs and lows. I have been here six years in total, which is a long time in modern football, and I'd like to say thank you to the fans for the support you give us – the players, the staff, everyone involved with the club.
'The warmth, support and kindness every time I meet a Bees fan has been amazing and it gives me extra energy to continue the work going forward.
'We attacked the Premier League in the first season and we're attacking it in our second season. I'm looking forward to hopefully continuing our progress and creating more magic moments together.'
Frank, initially appointed assistant head coach at the west London club in 2016, was promoted to the top job after Dean Smith's departure.
He led Brentford into the top-flight in 2021, finishing 13th in their first ever campaign in the Premier League.
Frank was nominated for Premier League manager of the season due to his team's performances.
Bees director of football Phil Giles added: 'I'm sure I speak for everyone at Brentford when I say that I am very pleased that we have agreed this new contract with Thomas.
'It is well deserved following some excellent results and performances in the last 18 months. Thomas has a detailed knowledge of the game, but just as importantly is able to inspire the players and build strong relationships with our staff.
'He has proven himself to be a Premier League-level head coach but retains an open-mindedness to keep learning and improving himself.'
