Brentford suffered a 4-3 defeat at home to Nottingham Forest to make it two losses from two in the Championship this season.
John Egan had given the Bees the lead with just over five minutes of the first half remaining.
However, the Brentford defence had a nightmare 10 minutes, surrounding half-time as they shipped three goals.
Andreas Bouchalakis scored fine finishes either side of the break with Daryl Murphy tapping in in between.
Andreas Bjelland did give Brentford hope in the closing stages before Kieran Dowell eventually put the game beyond reach.
There was time for Neal Maupay to pull a goal back before the end but it wasn't enough to rescue a point.
Below are six talking points to emerge from the game.
Warburton's quiet return
For all the talk on social media regarding whether to cheer or boo ex Brentford boss Mark Warburton, the reception was pretty tame.
I think the Nottingham Forest boss deserves some credit for that by going out with his staff and heading straight for the bench.
It was a different strategy than former Bees manager Martin Allen who sought the attention of the Griffin Park crowd.
Defensive frailties
When Brentford concede one goal they are liable to concede more in a short space of time.
On 12 occasions last season, the Bees conceded twice in the space of 10 minutes and it happened again at Griffin Park on Saturday afternoon.
As a defensive unit, Brentford should have cleared a Nottingham Forest free kick away but they allowed the ball to drop for Andreas Bouchalakis, who rifled a shot into the net, leaving Dan Bentley helpless.
Then they gifted Tendayi Darikwa a golden opportunity, only for him to hit the post and Daryl Murphy to tap home the rebound.
Brentford know they have to stop their heads from dropping at those moments and refocus to prevent this from being a regular issue again this season.
Dean absence
I felt Brentford missed Harlee Dean's presence in the side against Sheffield United when he was suspended but I felt his absence was felt even more against Nottingham Forest.
Dean was, after all, deservedly last season's player of the year and his leadership went through the squad.
He is also an excellent organiser and I feel he would have made sure the ball was cleared prior to Bouchalakis' first goal.
You can't use his contract dispute as an excuse. Jota is in the same boat and has started both games.
Attacking capabilities
For all Brentford's weaknesses at the back, they are a constant threat going forward and I wouldn't be surprised to see three goals scored often in a game.
The Bees create several chances and I have no doubt that there will come a time when an opponent is on the end of a hiding if everything comes off.
Set piece joy
One area where Matthew Benham and Mark Warburton disagreed on was the importance of set pieces.
It was ironic that two of Brentford's goals came from short corners with John Egan and Andreas Bjelland finding the net, the latter was awarded by goal line technology.
Perspective
Two defeats in a row is Brentford's worst start to the season since promotion to the second tier.
However, it should also be noted that Newcastle had a grand total of nil points at this stage of the campaign last term and they went up as champions.
The season is not won or lost in August. This Brentford team needs time to gel then I'm convinced that they will start flying up the table in rapid fashion.
