A Lasse Vibe brace was enough as Brentford recorded a deserved victory at the City Ground.
His brace and Jota’s goal was enough to see off Forest, despite late goals from Ben Brereton and Zach Clough.
Brentford made an electrifying start and should have been ahead early on.
Vibe had a chance after two minutes, but the Dane saw his left foot shot saved at full stretch by Jordan Smith.
Forest, shaken by Brentford’s fast start, sprung to life when Britt Assombalonga had an effort palmed by Daniel Bentley.
Then it was Bentley who started the build-up for Brentford’s opener.
His throw-in was taken by Jota and his run and pass released Vibe, and the Dane’s shot had too much power for Smith.
That gave Brentford a 1-0 lead after 17 minutes and it could have been 2-0 shortly after.
After Daniel Fox’s back-pass header found Smith, he booted his clearance straight to Vibe, but the Dane hit the side-netting.
Brentford took a 1-0 lead into the break, and they started the second half like they did in the first.
Sergi Canos’ rumbustious run found Vibe, and the Dane lobbed the ball over Smith and give Brentford a 2-0 lead.
Brentford needed a third to put daylight between them and Forest, and they did just that on 68 minutes.
Vibe played a one-two with Jota, and the Spaniard raced away and curled home in the bottom right corner to give Brentford an unassailable lead.
The duo were substituted on 76 minutes, and received applause from both sets of fans for their phenomenal display.
Forest, on the other hand, were simply dreadful and had no answer to Brentford’s attacking threat.
They did pull a goal back on 82 minutes through Ben Brereton.
Eric Lichaj’s cross-shot was palmed by Bentley, and the 17 year old tapped in to give Forest some pride.
Surely a comeback couldn’t have possibly been on the cards, but the home side scored another in injury time through Zach Clough.
The striker, signed from Bolton Wanderers in January, headed home from Ross McCormack’s cross but it wasn’t enough.
