Brentford boss Thomas Frank has agreed terms over a new deal.
The Sun says the deal is set to run until 2025, although the paperwork is yet to be fully signed off.
Frank's current terms were due to expire at the end of next season.
But the Bees are keen to tie their charismatic boss down for longer after a fine first campaign in the Premier League.
Brentford, who host Wolves on Saturday, currently sit 14th in the table, nine points above the relegation zone.
