Two days before the 11th A-League season kicks off, Gallop dwelt on the ugly confrontation with Professional Footballers Australia that threatened to throw the start of the competition into disarray.
On the day the PFA issued a statement urging the game to become more professional and better engage with all stakeholders, Gallop urged the union to sign to get on with signing a "good deal" for the players during the official launch of the competition in Sydney.
Later he told a media conference that the league will in all likelihood start with no CBA in place.
"I am frustrated at the time that it's taken," Gallop said.
"Indications from the PFA leadership are that the deal is agreed and needs to be ratified.
"We wanted that to happen last week and I certainly call on it to happen this week so we can settle in for the season.
"The bottom line is affordability. The deal that's been on the table is good.
"It accommodates the PFA's desire to see a whole-of-game CBA over four years, which means it deals with the Socceroos, Matildas and the A-League.
"I think it's agreed and it needs to be signed off ... but it should happen quickly.
"It's dragged on for too long and it's created some incredibly disappointing events around the Matildas and the Socceroos.
"I think it really is time for them to focus on their job and let us focus on ours."
Gallop said that he never doubted that the league would start on time even when at the height of the controversy strike action was mooted.
"I think the fans would expect the games to go ahead in any circumstances and I think the PFA recognises that as well," he said.
"And, yes, I'm saying the same."
Gallop took umbrage to the union's statement.
"I don't think it was a useful comment today," he said tersely.
"We're perfectly aware of what needs to happen to develop the sport.
"The PFA have got a role and right now their role is to get the deal done.
"It's got to be a deal that is affordable and responsible to the game."
The PFA later responded to Gallop's claim.
"The PFA has been working for 14 months with FFA to reach an agreement for a whole-of-game CBA," chief executive Adam Vivian said.
"It required players taking serious industrial action and the Matildas being forced to cancel a tour, for FFA to move.
"There remains a number of matters to work through, specifically relating to conditions. There are more talks planned for this week with FFA where we hope to address these.
"The PFA is the representative of the players. Once both parties' positions have been finalised and the players have been adequately consulted, provided feedback and made a decision we will be in a position to sign the agreement.
"We call on all parties to remain patient as we work towards this historic agreement that will impact on all our members' careers."
