The former Down man could see only good in his own side after the clash which saw 14-man Donegal ease past the visitors.
“Donegal had a lot of gamesmanship out there today, whether you like it or not,” said McGrath.
“Let’s call a spade a spade. I mean, the number of times Donegal players went down, in some instances feigning injury, just to stop the clock, to break the play up and the referee fell for it, he fell for it.”
McGrath was also angry at the two-minute delay in taking the penalty describing it as unacceptable.
“Let’s see what the authorities do about it. I mean, they will do nothing of course because it’s Fermanagh.
“If it was Dublin on the receiving end of it, they might do something about it, but because it’s Fermanagh, you know,” said McGrath.
The comments will surprise those who were at Mac Cumhaill Park to see all the off-the-ball nonsense from Fermanagh players, particularly by Sean Quigley.
TV replays showed him appear to get away with throwing a punch at Eamon McGee in the second half (it wasn’t mentioned on the Sunday Game commentary).
The big talking point following the clinical 2-11 to 0-10 victory by Donegal’s 14 men was the sending off of Neil McGee just before the break.
But Rory Gallagher defended the Gaoth Dobhair man.
“I thought I heard a whistle for a free out and Neil is adamant that he heard a whistle for a free out and then he kind of shrugged his man off,” he said.
