Match ends, Brentford 2, Swansea City 3.
Brentford head coach Thomas Frank likened his side's start against Swansea City to a "horror movie" before they eventually lost 3-2.
Swansea's dominant first-half performance saw them race into a 3-0 lead inside half an hour with goals from Wayne Routledge, Leroy Fer and a Chris Mepham own goal.
Brentford did pull the game back to within a goal with 20 minutes to play, courtesy of Ollie Watkins and Said Benrahma, but the Bees fell to a fourth defeat in their past five games.
"We took some momentum from the draw at West Brom, but then we went and made a mistake inside the first minute," Frank told BBC Radio London.
"We were 3-0 down after just three shots on target and you just think, 'this can't be happening'. It was like a horror movie and it got more and more scary.
"We showed fine character to get back into the game and you could say we deserved a point on the basis of our second-half performance.
"But, it's not good that we keep putting ourselves in these situations over and over again."
Defeat leaves Brentford ominously close to the Championship bottom three with just four points separating them from third-from-bottom Reading.
Frank's side were behind after just 25 seconds in when Routledge opened the scoring.
"Our defending's a concern and something we've been looking at for quite a while now," Frank added.
"Football is complex, a mixture of things like momentum, form, relationships, confidence and skills. We don't have the right recipe at this moment in time."
Victory for Swansea lifted them to 12th and their only disappointment in the early stages was the loss of Martin Olsson, who was taken off the field on a stretcher and replaced by Connor Roberts.
Potter will be relieved to see his side bounce back after three successive defeats.
Swansea manager Graham Potter:
"We were three up and doing things really well and then we conceded and the home crowd turned.
"We knew the game game was still alive and started the second half well, had chances to put the game to bed, but didn't take them and then anything can happen.
"Any three points will be hard fought in this division. We had a little luck and they missed some good chances so all in all it was a great game for the neutral, but horrible for me and their manager."
