Crawley manager Scott Lindsey apologised to the fans after they were thumped 6-0 at Swindon.
Jake Young scored four second-half goals as the Robins blew the Red Devils away, with Dan Kemp and Tyrese Shade also on target.
Former Swindon boss Lindsey said: “I can only apologise to the fans. The goals were embarrassing. Marking in the box is something that I worked on tirelessly.
“But for one of the goals there were four men around Young yet he gets in between them all and nods it in. It’s the easiest goal he will ever score.
“Players out there didn’t do their job properly. And that’s why you come to a place like this against a really good side in Swindon and you get punished.
“We won’t be forgetting it. We’ll be using it to learn from. You know, we have to watch it back. We have to break it down. Look at it and understand it.
“And how do I approach this week? It’s called hard work, which the players didn’t do today.”
Danilo Orsi gave Swindon a massive let-off within 10 minutes as he was given the ball free in the middle of the box, but shot over.
Swindon took the lead after 34 minutes as Young and Kemp exchanged passes on the right, with the latter being slipped in behind to coolly finish across Corey Addai.
Young made it two, two minutes into the second half, when he raced beyond the Crawley defence and tucked the ball away at the near post.
Swindon were flying as after 51 minutes Kemp won the ball high and fed Young to slam home a third goal and he had his hat-trick on the hour mark as he tapped home at the back post.
Young added his fourth after 71 minutes as Tariq Uwakwe crossed to the back post and he leapt up to head home, before Shade converted in stoppage time.
Home boss Michael Flynn refused to get carried away after his team’s magnificent second-half performance.
Flynn said: “I thought we were fantastic, we could have scored more and we started sloppy and they should have gone a goal up, if I am brutally honest.
“Our passing went amiss, and we were getting caught on the counter as we were leaving too many gaps.
“It is important (not to get too high or too low) and you learn that through experience, I was like that as a player.
“It is an emotional game, but sometimes you have to put that to the side and be professional.
“After last week’s shenanigans (drawing 5-5 against Wrexham) I will never take being three or four-nil up for granted.
“I have got faith in my players and I knew that today would not be a repeat of what happened last week.”
