In a dramatic encounter at nib Stadium, one decided by Mark Bridges' solitary strike, there was still plenty of thrills and spills as Perth laid siege to Sydney's goal after half-time.

But there were more fireworks to come after the game as Sydney defender and former Glory player Coyne, exchanged words with his old coach Ferguson while players left the field.

Coyne still appears angry with his treatment by Perth. A former Glory skipper, the 30-year-old was dropped for the final seven matches last season, reportedly due to a clause in his contract, which would have seen him automatically re-signed by Glory for a year if he played one more game during the 2010-11 campaign.

Coyne wasn't in Ferguson's plans as the coach looked to rebuild his disappointing squad from last year, but the 30-year-old defender couldn't help expressing his unhappiness with what transpired to the coach after helping his new team to victory.

"That's football, heat of the moment stuff and things get said," Ferguson said following the game.

"We'll keep that private between me and Jamie Coyne. It's the same with players and coaches, we'll all have agreements and disagreements and at the end of the day there was nothing in it, they said a couple of words and I said a couple of words."

As Ferguson and Coyne spoke to each other, Sydney skipper Terry McFlynn came over to separate the pair, although he also felt there wasn't too much in the incident.

"I think that's something that's a personal issue between them two, it's not football related," McFlynn said.

"I don't want to speculate or comment on people's own personal situation 'cause I don't know the facts but at the end of the day, emotions run high and we came here to get three points, we got three points and recovery starts now for Central Coast."

Coyne's new coach at Sydney, Vitezslav Lavicka, praised his defender for keeping his mind on the job, especially during a frantic second half when Perth mounted a flurry of attacking raids.

"Of course, it was a special game for Jamie because he's coming back to play against his previous club," Lavicka said. "This is always emotional and a bit special.

"But I was seeing an article this morning in the newspaper about him and he said, well, he's coming not to do the revenge for Glory, but he's going to do his maximum for Sydney FC to reach a good result and it was a great answer from him."
