Gary Hamilton said he was “frustrated” by Glenavon's Friday night's draw with Mid-Ulster rivals Portadown.
The visitors had largely dominated the game at Shamrock Park but fell behind to a 92nd minute goal from Portadown's Paul Finnegan.
But, just as the game looked to have slipped from Glenavon's grasp, a stunning free kick from Michael O'Connor rescued a point for the Lurgan Blues a minute later.
“I'm frustrated but on the flip side the boys showed great character,” said Hamilton.
“It was a great free kick from Mick. I thought he was excellent – along with Skimmer [Matthew Snoddy] they ran the show.
“I'm disappointed because I felt our overall performance deserved three points. But when you go a goal down so late on and get an equaliser then you're happy.”
Glenavon thought they had taken an early lead when Matthew Fitzpatrick put a spectacular overhead kick in the back of the net on two minutes, but it was ruled out for offside.
Later, Danny Purkis could have broken the deadlock but rolled a shot past the post, while the busy Kyle Beggs had a volley blocked by Adam McCallum.
The Ports had a couple of decent first half chances too despite Glenavon's dominance. Lee Bonis was unluck.
When Finnegan tapped in at the back post in stoppage time, the 450 travelling Glenavon fans must have been wondering how they were about to lose the game.
However, O'Connor's sublime free kick curled into the top corner, past Harry Doherty, to send them into raptures.
Glenavon have a week-long break until their next fixture against Warrenpoint Town at Milltown.
