The Perth Glory coach is no longer muted and will return to the sideline for the big game against Sydney FC at Allianz Stadium on Sunday.

He was relegated to the grandstand and forbidden from match-day contact with his players as a result of his finger-pointing rant at referee Alan Milliner at halftime of the round-three game against Melbourne City.

Lowe admitted he over-stepped the mark on that occasion.

His passion means he is often great theatre on the sideline and his media conferences are very entertaining because he has a terrific personality and says what he thinks.

Asked if he saw himself as actively promoting the game and whether he regarded that as one of his responsibilities, Lowe told The World Game: "I think so, as long as you do it the way I do it in the press conferences and not the way I did it on the pitch.

"You've got to promote the game in the right way. I just think it's pointless being bland and cliched, you're not saying what you're actually thinking.

"I think if you've got something to say, say it, and try to say it in a way that doesn't upset people, and if you can have a laugh along the way, hey, why not?"

Lowe said he was just being himself.

"If you try to be somebody you're not, eventually you get found out," he said.

"I just call it as I see it, as best I can, and I guess there has always been a bit of humour there, or a bit of sarcasm. Where I came from, all my mates were like that, so if you didn't get in first then you got done."

Lowe became something of a cult figure when he first emerged as an A-League coach, because he was so lively on the sideline, but he said he had made a conscious effort to bring the level down there.

"It's good to be a character, but not a caricature," he said. "Early on when I got in I was jumping all around in the dug-out and I tried to calm that down a little bit.

"Now that I've done that, maybe you get people to look at you for the right reasons, that you can actually do the job."
