Best team in the world in ODIs?

Tweet

Aussies beat India and England rather convincingly. Now England go on to beat South Africa easily. Do you think Australia has again opened a gap over the other teams in terms of superiority. Even with a literal B-Team, they managed to beat India in Indian conditions. They also thrashed England 6-1 and lifted the Champions Trophy. Are they back at their best and are they a cut above the rest? Cheers! Ram
