Australia vice-captain and bowling spear-head Pat Cummins said teammate Glenn Maxwell will be a vital cog in the team as the all-rounder's performance would hold the key to their aspirations of winning the sixth World Cup.

Australia has won back-to-back ODI series -- in India and against Pakistan -- in the run-up and Glenn Maxwell has played an important role, hitting three half-centuries in their 5-0 series win in the UAE.
