After winning the first match by 5 wickets, Team India will surely win the second ODI match to clinch the series with one match in hand. In the last match we saw that everyone did very well from their respective positions especially the opening pair played their best so I think Team India can go into the field with an unchanged XI for the second ODI against Australia.
They won't surely win because their opponent is Australia who shouldn't ever be taken for granted. I feel India definitely has the advantage, but Australia could bounce back which is why this one could go right down to the wire.
India has the better bowling lineup while Australia has the better batting line-up. Excited for this encounter!
