Adam Barrett has discussed his "frustration and disappointment" after Millwall succumbed 3-2 at Brentford in the Sky Bet Championship, in what is due to be The Lions' last visit to Griffin Park.
Three late goals from Josh Dasilva, Bryan Mbeumo and Ollie Watkins gave the West Londoners a shock victory in the closing minutes, after Tom Bradshaw and Jed Wallace (pen) notched for The Lions - bolstered by Bartosz Bialkowski's penalty save to deny Watkins in the first half.
"I'm really frustrated and disappointed with the way we finished the game," Barrett said to millwallfc.co.uk.
"At 2-0 with not long to go, I thought we looked comfortable. But they caused us problems and they're a good side, they make it difficult and move the ball really well.
"I thought the work-rate from the lads was tremendous, but our game management at the end there has to be much better. It was frustrating because they had their tails up the minute we let them back into the game. From a throw-in and then one pass, they get a shot on goal for the first one; the second goal gets a wicked deflection, and we really have to be seeing games out better from great positions away from home."
The caretaker manager says his side showed long spells of an impressive display, and praises the performance of goalkeeper Bialkowski in particular, but credits Brentford for their style of play under Thomas Frank.
"Brentford has always been a tough place to come - a good side with quality players in their team. I thought we defended really well in the first half, putting out bodies on the line and getting several blocks in.
"But, like I said, you can't be giving teams a sniff like that late on - especially sides who play the football that Brentford do. We know they had the lion's share of the ball, but at 2-0 up, we can't be coming away from here without points.
"Bart has been very impressive. He's a great shot-stopper, really calm and influencing at the back, and he was superb here. I'm disappointed for him, because he doesn't deserve to be on the losing side at all."
Barrett finally elaborates on the need for The Lions to improve in game management situations, and looks ahead to a quick turnaround as we host Cardiff City on Tuesday night at The Den.
"Moving on from here, we have to do better. This has happened too many times, this year and last year as well, and we need to manage these games and be seeing them out.
"We have good players in the dressing room - good, strong characters. It's just a little bit of game nous at times, which we have to immediately improve with.
"In this League it comes thick and fast, you can't dwell on it. We have another big game back at The Den on Tuesday and we need to make sure the lads recover well - of course Cardiff played the night before us - and we'll make sure we're prepared."
