Thomas Frank made eight changes to the side who lost 2-1 against Manchester City at the weekend.
It was Fabio Carvalho who made the most impact as the Bees came from behind to beat Leyton Orient in the third round of the Carabao Cup.
The 21-year-old winger joined from Liverpool last month in a deal worth £27.5m including add-ons.
His first Brentford goal came via a superb overhead kick from close range after Kevin Schade‘s effort had bounced up in the box.
Carvalho then provided a brilliant assist with a lofted ball into the box which Mikel Damsgaard converted for his first Brentford goal.
With Yoane Wissa out for a few months due to an ankle injury sustained against Man City, it could be a chance for Carvalho to force his way into Frank’s thinking.
His brilliant performance against Leyton Orient will have certainly helped his case for more minutes in the Premier League.
