The 28-year old New Zealand international is currently plying his trade with the Pilgrims in England's League One but hopes that one day he can force his way into the top flight before a potential return down under.
"I would never say never to A-League. It's like the American League (Major League Soccer), it's really coming along well," he said in an interview New Zealand TV.
"The quality's getting a lot better. But I just feel at the peak of my career, I've worked so hard in my life, for me it's the [English] premiership at the moment - that's all I've got in my sights. If I don't make it, at least I'll know I gave my 100 per cent to try and get there. I don't want to come to the end of my career and have regrets - `could I have worked harder?'
"I want to know in my own mind, `yeah, I've worked my hardest, I gave it my best shot and it wasn't to be'."
Fallon is currently back in New Zealand where he will join the All Whites for training camp before heading to Melbourne for a friendly in late May and then onto Europe before bunking down in South Africa for the World Cup finals.
