Moore spent two seasons at Newcastle before joining Queensland Roar as their marquee star for the coming year.

He left the English club just before new boss Allardyce went on a spending spree bringing in a host of new faces.

Despite boasting stars like Viduka, Michael Owen, Obafemi Martins, Alan Smith, Albert Luque and Shola Ameobi, Newcastle have now gone six months and 560 minutes of game time since their last goal at home.

Now Moore believe Troisi should be given a first team chance upfront.

"Personally, I like him. He's an exciting player and has a lot to offer," Moore said of the Adelaide-born striker.

Moore believes it is time for the Aussie youngster to be given a chance to shine alongside fellow Aussie Viduka and break United's dismal scoring record.

"Sam has been known in his managerial career to give players every opportunity and as a player, that's all you can ask for," he said.

"As long as you're given that opportunity then it's up to yourself whether you take it or not.

"I think James has got a very good future at Newcastle."

Troisi, the 19-year-old who made his senior debut in a recent pre-season victory over Hartlepool United, made the Magpies' bench in both the Premiership and Europe last season.

He told the club website: "I want to try and get in the first-team this year and I believe in my own ability."

Socceroo Moore, 31, also said his former English Premiership club needs consistency if it is to be become one of England's big four.

"You look at Man Utd, Chelsea, Arsenal, Liverpool and they're the benchmark," he said. "For me, it's a consistency thing. Those four teams are a lot more consistent.

"They say it every season that potentially Newcastle could be anything. Fantastic support, very passionate about their football and they would love to be doing better.

"Unfortunately the last couple of seasons, with UEFA Cup and what have you, they just seem to be missing extra, something special. I don't know ..."

Moore is making the most of being back home in Queensland and playing club football for the first time in Australia.

And with the advent of the A-League, he's urging caution to those youngsters who are thinking of moving overseas to further their football career.

"I was very fortunate, I was one of the success stories. There are also a lot of failures," he said.

"You may have the ability but you also need that bit of luck. There's not a mad rush if you're not going to better yourself."
