There is no equivocation about this, Dave Warner is universally criticised by all opponents for overly personal and unneccessary abuse and sledging. His needless send off for AB De Villiers' and de Kock's run out was stupid.
He is the instigator for bad blood.
I think he should be sacked from the vice captaincy immediately. If Smith is ever injured, Warner is supposedly the leader. He is an immature idiot who cannot control his emotions.
Tim Paine should be installed as vice captain immediately. Paine is now doubtless the incumbent wicketkeeper. He is universally recognised as the best glovemen in Australia by his peers has has adopted leadership roles before.
Adam Voges was a much needed calming influence in his short career too.
