The one thing Socceroo Adam Taggart knows is how to score goals.

The 21-year-old striker won't start ahead of veteran Tim Cahill at the World Cup but should he get his chance off the bench in any of the group games against Chile, the Netherlands and Spain he's got one sole mission.

"I think the only I thing I do is score goals, I can't really do much else.

"Me personally as a striker goals are something I'm always focusing on. Away from training it's something I'm working on all the time," he said.

"Come the games, if I'm on the park that's the only thing I'm thinking about.

"Just like the keeper with keeping the ball out of the back of the net, I feel I can contribute by putting it in the back of the net."

Taggart proved his prowess in attack during a blistering A-League season with the Newcastle Jets where 16 goals earned him the golden boot award.

With Jets marquee man Emile Heskey set to be leading the line, Taggart appeared destined for a season on the left wing.

But just like an injury to Heskey allowed Taggart to shine front and centre in attack, an injury to Josh Kennedy made him an unlikely inclusion in the final World Cup squad.

Taggart was given a very brief opportunity against Croatia last week and is ready to cross the white line again.

"For me it's about everyday training and if you get the opportunity you need to be ready.

"Everyone is involved in training every single day to make sure that whoever is called upon will know their job and their responsibility in the team." - AAP
