Brentford overturned a first-leg deficit to beat Swansea City 3-2 on aggregate and book their spot in the Championship play-off final at Wembley.
Ollie Watkins’ composed finish in the 11th minute levelled the semi-final on aggregate, and a header from Emiliano Marcondes put the Bees ahead in the tie four minutes later.
Bryan Mbeumo volleyed in a cross from Rico Henry in the first minute of the second half to make it 3-0 on the night and give Brentford a two-goal cushion.
Rhian Brewster dragged Swansea back into the contest with 12 minutes remaining, capitalising on a poor clearance from Pontus Jansson and chipping home goalkeeper David Raya, but the visitors were unable to find a second goal which would have forced extra-time.
Victory meant the Bees signed off at Griffin Park, their home of 116 years, in style before their move to a new stadium this summer.
The west Londoners, who are looking to end their 73-year exile from the top flight, will face either Cardiff City or neighbours Fulham at Wembley on Tuesday, 4 August.
Fulham will take a 2-0 lead into the second leg of their semi-final tie on Thursday (19:45 BST).
Early Bees blitz turns tie around
Andre Ayew had given Swansea a 1-0 lead at the end of Sunday’s first leg, and Brentford head coach Thomas Frank promised his side would attack from the off in a bid to reach the final.
Marcondes tested visiting goalkeeper Erwin Mulder in the fourth minute with a swerving shot from outside the box, and the Bees went ahead following a swift counter-attack from a Swansea corner.
A defence-splitting pass from Mathias Jensen put Watkins through on goal, and the forward made no mistake to net his 26th goal of the season.
The hosts swiftly doubled their lead when Said Benrahma picked out an unmarked Marcondes in the box to guide in a header from 12 yards.
Bees keeper David Raya preserved his side’s advantage with a low save from Conor Gallagher’s side-footed effort and Benrahma almost made it 3-0 on the night with a shot which hit the inside of the post.
Swansea fall short
Swansea boss Steve Cooper made a double change at the break in a bid to get back into the match, but his side fell further behind within a minute of the restart when Frenchman Mbeumo notched his first goal in eight games with a clinical volley.
Wing-back Connor Roberts cut in from the right and saw his left-footed effort tipped over by Raya as the visitors sought a way back into the match.
Brewster rarely had a sight at goal but calmly lobbed Raya from just outside the box after centre-back Jansson made a mess of an attempted back-heel. It was the striker’s 11th goal since moving to Swansea on loan from Liverpool in January.
Swansea continued to press forward and six minutes of stoppage time brought further drama as Brewster tested Raya from 25 yards, while Roberts and Bees boss Frank were both booked after a clash on the touchline.
Benrahma almost finished the match off with a flourish but saw a curling effort go narrowly over the bar.
Swansea were among the early pace-setters this season, but fell out of the play-off places in January and only just clawed their way back into the top six on a remarkable final day of the regular campaign.
Despite their play-off exit, Cooper, who led England to the Under-17 World Cup in 2017, will have positive experiences to build on following his first year of senior club management.
Brentford move closer to defining promotion
Brentford had propelled themselves into contention for automatic promotion following a seven-match winning run after lockdown, but missed out on a place in the top two after defeats in their final two games of the season.
They were the top scorers in the Championship this season and were back to their attacking best during a stirring first hour, before Brewster’s goal tested their defensive resolve in the closing stages.
The Bees have never won promotion in their eight previous play-off campaigns and have lost three finals, the most recent of which came in the third tier in 2013.
If they end that run, they will move into the Brentford Community Stadium, a 17,500-capacity ground, as a Premier League club.
