Canberra Olympic coach Frank Cachia said a national division-two football competition with a promotion and relegation system to feed the A-League is unlikely to succeed.

The eve of the A-League season and the latter stages of the FFA Cup prompt the yearly discussion about the need for a national second-tier competition to increase the talent pool, but Cachia said the creation of greater regional divisions would be more realistic financially.

"The biggest thing for me with a second division is you need to have teams in there that are ready to step into the A-League if they do win promotion," he said.

"The reality is, with anything like that, it costs because clubs would have to fund travel and player payments."
