United’s boss was left enraged by referee Mike Dean’s decision to overrule linesman Jake Collin’s offside call and allow Jonny Evan’s own goal to stand, giving the Magpies a 2-1 lead at half-time.
Dean chose not to send the Scot to the stands and has left his altercations with the manager out of his post-match report, but Pardew feels the Football Association should take retrospective action.
“I think Mike Dean might feel slightly disappointed he didn’t do something about it,” Pardew told The Guardian.
“I think the pressure that was on him was tough for a referee to take. Sometimes when you reflect on a game you think you might have acted differently. You do that as a manager and I think he might have done that as a referee.
“But it’s an emotional game and apparently they had a cordial discussion. I’ve had a few of those myself and sometimes I’ve ended up in the stands as a result of that cordial discussion.”
Pardew was also angered that the FA missed Toon defender Fabricio Coloccini allegedly receive a blow to the face from Reds striker Robin van Persie.
He added: “I think there were a lot of things the FA could look at. But it seems they are looking at none.”
The defeat at Old Trafford has left the Magpies in 15th place, five points above the relegation zone.
