Essendon president Paul Brasher has returned serve to Greater Western Sydney football manager Jason McCartney following the two clubs' dealings during the trade period.

McCartney was left frustrated with how the Bombers went about their business in dealing for Giants young gun Jye Caldwell, who eventually got his move to Essendon in the dying seconds of the trade window.

“The Caldwell one was a millimetre away from not getting done either,” he told The Sydney Morning Herald.

“That’s Essendon: Target a player, high quality, get him in the door, and then not (be) prepared to stump up the price to actually facilitate the deal.”

Brasher stated that McCartney's comments were "unprofessional" after a deal between the two clubs had been agreed upon.

“We’re really, we’re disappointed with (not getting) Josh Dunkley, we’re happy we’ve got three good players you know I think will be ready to go and make an impact,” Brasher told The Age.

“I think Adrian (Dodoro) and his team have done a great job, we’ve got (picks) 6, 7 and 8 going into the draft and we’ll use those. I was really annoyed to hear him criticised externally.

“I thought it was sour grapes and I thought it was unprofessional and it was a bit like, you know, the kid going home and crying to mum that the other kid didn’t play fair – in fact, the deal he complained about is exactly the deal he ended up doing .

“I don’t know how you explain that. I can’t.”
