Paulo Di Canio insisted he was anything but content after watching his Swindon side end a three-game winless run at Stevenage.
Goals from Matt Ritchie, Raffaele De Vita, Miles Storey and Adam Rooney inflicted a heaviest-ever Football League defeat on high-flying Boro - their first at home this season.
Three goals came in an impressive first-half performance in which the Robins might have scored more, with Tommy Miller having a penalty saved by home goalkeeper Steve Arnold.
But rather than leaving Di Canio delighted, the display only served to highlight to the Italian what his players had failed to deliver in recent weeks.
"The performance was good, I'm happy with the three points, but obviously I'm not completely happy. I'm more angry than ever. You can imagine why," said the Swindon boss. "I've asked my players, why did they switch off for three or four games. Because the secret wasn't that we played better as a team - that was clear. But because every individual behaved 120 per cent.
"Fortunately, thanks to the players, we've scored four very good goals - which we deserved. That's why I'm angry with them, because they're capable of this."
