In an interview with the West Australian newspaper last Sunday, Sage declared he'd had enough, after Glory's 2-1 loss to Melbourne Heart on Thursday night sparked a torrent of abuse from some sections of the nib Stadium crowd, aimed at the owner, coach Ian Ferguson and the players.
But in an open letter to fans this morning ahead of the clash with Central Coast, Sage apologised wholeheartedly for the comments.
"I feel the agony and bitterness of defeat when the team loses, and like many passionate fans, I experience a roller-coaster of raw emotions throughout each season," Sage wrote.
"There are times when that passion, mixed with a healthy dose of frustration and a burning desire for improvement cause my feelings to overflow.
"Sometimes I speak out in response to what I regard as ignorant or ill-informed attacks on the players and coach ... At times like these I've been known to express my views openly in public, and perhaps unwisely, to the media.
"Recently I made some comments in an interview which I now regret.
"These comments were reported correctly and in full and I know the interview created headlines in the Perth newspapers and generated a strong response from our supporters and members, but at the end of the day I now regret making the comments attributed to me and I wish to affirm my intention of remaining the owner of Perth Glory.
"I regret suggesting that I intended to depart the club, and I apologise to any members, supporters and sponsors who may have been distressed by these comments.
"I'd also like to thank the hundreds of Glory supporters who contacted me directly with messages of support.
"Believe me; such support is very sincerely appreciated and certainly focused my mind on the huge amount of fans that would have been affected."
Glory coach Ian Ferguson took it on himself to call on fans to direct their anger at him and not the team or owner if results continued to be poor for the club, who have now won just one of their last eight games after another bright start to the season.
And, while Ferguson admitted he's feeling the pinch, Sage declared his support for the coach in his letter.
"Ian, in my view, is a coach who, together with his coaching staff, is doing his utmost to bring success to Perth Glory," he wrote.
Sage has been the exclusive owner of the club since Brett McKeon sold his share to the mining magnate at the end of the 2008-09 season.
