The victors will join Leeds United and West Bromwich Albion in the Premier League next season.
The game is often termed as the ‘richest’ in football owing to the riches of the top flight which it brings and has only increased over time due to rising TV and broadcast revenues.
Thomas Frank’s Bees ended the season in third and overcame Swansea City over two legs to book a place at Wembley.
The Cottagers finished fourth and beat Cardiff City in their semi-final as Scott Parker attempts to lead the Craven Cottage outfit back to the top flight.
For Brentford, it will be their fourth play-off final and first since 2013 when in the third tier.
The Bees have lost each of their three play-off final matches and should they fail to gain promotion once more, they will have taken part in more unsuccessful play-off campaigns than any other side.
Fulham meanwhile have reached the Championship play-off final for the second time in the last three campaigns.
And the clash will pit joint-Championship top scorers Ollie Watkins and Aleksandar Mitrovic against one another.
With 90 minutes of the season remaining – and the potential for extra time and penalties – only one of these sides will be a Premier League team when the 2020/21 campaign kicks off in mid-September.
With that in mind, here’s how you can watch the clash at Wembley.

How did both games end earlier this season?
The omens are positive for Brentford after doing the double over Fulham earlier this season.
At Griffin Park in mid-December, Bryan Mbeumo’s goal was enough for the Bees to secure all three points.
And when these two sides met at Craven Cottage in the first Championship game to be played behind closed doors when the division resumed in mid-June, it was the Bees who again emerged victorious.
Late goals from Said Benrahma and Emiliano Marcondes ensured victory as the Bees did the double.
What are the match odds?
According to The Pools, Brentford are 23/20 to emerge victorious while a Fulham victory is priced at 5/2.
A draw is priced at 23/20.
