The Magpies chief felt compelled to pull Yohan Cabaye out of Monday night's 4-0 defeat at Manchester City after news of Arsenal's bid for the midfielder, believed to be around B£10million, became public.
Pardew did not believe Cabaye was in the right mental state to do himself justice and sent him back to the north-east ahead of his side's hammering at the Etihad Stadium.
In addition to his annoyance at Arsenal for failing to show his club some respect in their transfer dealings, Pardew also believes it highlights a flaw in the transfer window, with clubs at risk of losing their key men after the campaign has got underway.
"There is a question about the window being closed before we kick off the Premier League season," said Pardew.
"I know the Premier League asked the European leagues to do it and they wouldn't fall in line.
"But after the summer we have had, the situations we have had, with Rooney as well, it is definitely something they need to put under the microscope again."
Other than shoving the season back to the beginning of September, it is impossible to imagine a plausible solution.
Yet it is hard not to feel some sympathy for Pardew either given how badly timed Arsenal's approach was.
"I didn't see any reason why that needed to happen," said Pardew.
"When you do a pre-season like we have and been very thorough and prepared for three days with a team that includes Cabaye, it is tough for his head to be turned on the eve of a game.
"Why they couldn't do us the respect and the honour of waiting until Tuesday evening is beyond me."
Pardew could have asked Cabaye to play.
But he felt the Frenchman, who has also attracted interest from Manchester United this summer, would have found it impossible to concentrate.
"It is a very difficult situation and hard to get your head round to play a game of this magnitude," he said.
"It is pretty obvious I am upset about it.
"I am not sure of the exact terms of it (the bid) but it is below our valuation for sure," said Pardew.
