this whole tour has been really spikey, can understand tensions are building because of all the quarantines and bubbles they have to be in but they werent exactly on friendly terms before.
Some of the aussie players behaviour was awful, Paine has done himself no favours, but i am sure both sides are guilty of it. Kohli isnt exactly a shrinking violet on the pitch so maybe not in the best place to criticize. Dont disagree with Paine on Ashwin though, he's a bell of the highest order.
If there was racist abuse by the fans thats appauling, and should be dealt with. The Gabba wont be much friendlier though i wouldnt imagine after the way this test has ended.
