Brentford head coach Thomas Frank has signed a new long-term contract at the club, which will see him extend his stay until the summer of 2025.
The Danish boss was due to see his contract expire at the end of the season, but the Bees have moved to extend his stay with the Premier League new boys.
The 48-year-old was appointed Bees boss in October 2018 and guided Brentford to promotion from the Championship last season to take the club into the Premier League for the first time.
The Bees have also reached a Carabao Cup semi-final, as well as a quarter-final in the same competition and the fifth round of the FA Cup in 2019.
Frank's assistant Brian Riemer has also signed a new contract until the summer of 2025.
Phil Giles, Brentford Director of Football, said: 'On behalf of everyone at Brentford, I'd like to congratulate Thomas and Brian on their new contracts.
'First and foremost, they are fantastic people to work with and I'm sure everyone at the club will be pleased that they have committed to stay with us until 2025.
'They have been integral to the success that we've shared over recent seasons, culminating in achieving our shared target of playing in the Premier League.
'We want to continue to take Brentford forward, to compete with clubs far bigger than us, and to see how far we can progress.
'I am sure that we can build on the success that Thomas and Brian have helped deliver along with all of the other staff and players and look forward to what I hope will be a successful conclusion to the season and beyond.'
Brentford have won six games in their first top-flight campaign since 1947, including victories over London rivals Arsenal and West Ham.
The Bees currently sit 14th in the league table, but will be hoping for an improved second-half to the campaign.
They have however mustered up just seven points from their last 10 matches, leaving them 18th in the form table.
