Nottingham Forest inflicted a first home defeat of the season on Brentford as they maintained their push for a European place.
Goals from Ola Aina and Anthony Elanga, as well as some resolute defending, helped Forest to their third consecutive victory.
The result also lifts Nuno Espirito Santo’s side up to third in the table, a point above fourth-placed Arsenal, who travel to Crystal Palace later on Saturday (17:30 GMT).
Having withstood some early pressure from the hosts, Forest opened the scoring towards the end of the first period when Neco Williams got down the left and his low cross was placed into the bottom left corner by Nigeria full-back Aina.
The visitors added to their tally shortly after the break when Elanga capitalised on a mistake from Keane Lewis-Potter and drove into the penalty area before dispatching his effort past Bees goalkeeper Mark Flekken into the bottom left corner.
It proved a frustrating afternoon for Brentford, who came into the contest with the best home record in the English top flight, having won seven and drawn one of their previous eight fixtures.
However, while the Bees enjoyed plenty of possession, they ultimately lacked a cutting edge in front of goal.
Mikkel Damsgaard and Yoane Wissa were both unable to convert first-half opportunities to give Thomas Frank’s side the lead and Kristoffer Ajer’s close-range effort was superbly repelled by Forest goalkeeper Matz Sels as the hosts looked for a way back into the match.
They drop down a spot to 12th in the table, having lost three games in seven days.
