Tim Cahill is adamant he doesn't need playing time to make Australia's World Cup squad.

The former Everton striker recently signed with his first professional club, Millwall, after leaving Melbourne City earlier in the season.

But the 37-year-old has stressed his time at Dens Park will help him to prepare for Russia, regardless if he plays a significant number of minutes.

"I don't think it's about playing. Hundred per cent it's not," Cahill said.

"Everyone says 'oh, you gotta play, gotta play to get to the World Cup'. Lets just put the World Cup aside.

"This is about being in a professional environment that tests me every day. And hopefully, touching wood, no injuries."
