Harold said Roar players shouldn't exect the kid-glove treatment from the Englishman who has vowed to turn around the fortunes of the club, currently languishing in ninth spot.

But with Glory heading to Suncorp Stadium tomorrow, the 20-year-old is hoping his former mentor from the now defunct Gold Coast United takes at least a week to get the Brisbane outfit firing.

Mulvey replaced Rado Vidosic who has been shifted to the role of Technical Director after a string of poor results.

“He’s a great motivator,” Harold said. “He gets players going in the change room which might be what is necessary to get Roar back on track this season.

“It will be interesting to see in the coming weeks how they respond to his appointment. He’s certainly had a big influence on my career.

“He was stern when he needed to be but that’s why I think he had so much success. He tells players what they need to know. That may be hard for some players to take but it needs to be said.”

Mulvey coached the promising striker for two years in United’s youth set-up and again in the senior team during the club’s final turbulent weeks. And Harold believes he’s earned another shot at the A-League.

“We were part of a club that was pretty much going down the sink and he had to keep everyone motivated to play every weekend so that we didn’t slack off or have all this negativity,” he said.

“He kept the club going after Miron (Bleiberg) left and we managed to string some decent results together towards the end of the season with the majority of youth team players under the age of 21.

“That’s what he’s proven in the past - that he can manage young players and get the best out of them.”

Since joining Glory in the offseason Harold has had to bide his time, earning just one start this season in an outfit that has struggled for goals.

Coach Iain Ferguson has talked up the young player, describing him as “always dangerous” and “a threat” but that hasn’t translated to game time, with the Brisbane native forced to make his mark from the bench - something he did to lethal effect in Glory’s 3-2 victory over the Jets in round five, scoring the late winning goal within minutes of crossing the line.

With four other former Gold Coast players in the Perth line-up, Harold admits fitting into the squad has been relatively easy, but less so the wait for his chance to shine.

“As a professional footballer you want to be in the starting team every week,” he said. “You want to be playing 90 minutes.

“But considering I’m at a new club I’ve had to prove myself to the coach and I feel that every game I’ve been involved in I’ve made a good impact off the bench.

“And for me to get a spot in the starting team I’ve got to keep doing that. Obviously it’s frustrating but you can’t dwell on that.

“You just have to keep working hard and show the coach that you’re ready to get in the starting team.

“That’s part and parcel of being a professional athlete. You’ve got to be very determined and switched on all the time.”

Perth snapped a five-game winless streak with a 3-0 drubbing off the Jets last weekend and Harold is keen to help his club cement their place in the top four when they head to Suncorp.

“I’m expecting a really tough game but I’m looking forward to it, hopefully I can get a few minutes,” he said.

“I’m just looking forward to being back in my home town as well – it would be great to get a goal as well.”
