Instead, the Reds manager stored up his frustration until after the game was over, and then directed it to TFC GM Tim Bezbatchenko.
On Friday Bezbatchenko sent a blunt message to his team, saying it needed "to take it up a notch,” after the Reds had only earned 13 of a possible 33 points since July.
Nelsen fired back on Saturday, accusing Bezbatchenko of effectively sabotaging his own team.
"I've won this league, played in it for four years, been in the [English] Premier League for 10 years, played in a World Cup, Olympics. I've played in some pretty hot pressure games," said Nelsen, a former New Zealand international defender. "One thing that I do know is this was not one of them."
"It affected the guys," he said of Bezbatchenko's words. "What we do at Toronto FC is we keep it in-house — everything we do, we keep inside the four walls. And the players, coaching staff, everything, stays within the four walls."
So do you agree with Nelsen?
