Griffiths has continuously been overlooked when it comes to international football, but the reigning A-League premier and Johnny Warren Medallist is confident he can turn that around.
Speaking to the Sydney Morning Herald, he said, "I'm going into the game (tonight's friendly vs. Ghana) with nothing to lose, I know we're a little bit short on strikers at the minute, and with a good performance, I could be in the camps for the next month or so.
"You've got to be confident in your own ability. I'm pretty confident and I'm feeling pretty good, and hopefully we can have a good result for myself and the team."
Griffiths had a positive stint with Japanese second division club Avispa Fukuoka, despite a red card in his final match and difficult relationships within the inner sanctum.
"A lot of players didn't agree with the gaffer (coach Pierre Littbarski). It sort of split the team in half, and it was really hard for the foreigners when you knew some players weren't giving 100 per cent.
"It wasn't a happy dressing room, there was a lot of cancerous people in the sheds and it was going through the whole team, including the staff.
Although there was tension in the air, Griffiths enjoyed his time in Japan and would consider further opportunities in the J-League.
" I enjoyed Japan so much, if I could go back there, I probably would. The lifestyle is very good, my wife enjoyed it, we had a ball. I'd give it another shot with another club because I just like the way they play football and I felt I adapted."
