Australian captain Pat Cummins on Thursday said the Border-Gavaskar Trophy against arch-foes India is going to be more "attritional" as the two heavyweights of world cricket will be sparring over five Test matches instead of the traditional four games.

The blockbuster series will be a survival of the fittest as Australia look to avenge successive losses on home soil when they go head-to-head from Friday.
"Border-Gavaskar Trophy has always been very tight every series, five Test-match series gets really attritional, it's a big one really," Cummins said at the pre-match press conference.
