To be honest I dont know much about him except I have heard that he bats well in the State Game. Ricky Ponting is probable out for bothe physical & political reasosn. Firstly he broke his finger in Adealide & again didnt knock up a big score in Melbourne.
He is still regarded as the best captain around at the moment. He has come under incredible criticism from all and sundry over his recent batting performances as well as the teams generally.
Australia has not really replaced the trio of superstar players that retired a couple of seasons back.
It will be interesting to see how Khawaja performs and Australia generally with Ponting in the Sydney Test.
