Not only Australia but also World Cricket has lost two of All-Time-Greats in Warne and McGrath. To be honest, Australia's enviable position as Number One has much to do with these gentlemen and I doubt if Australia can retain its Number One position going forward.
We all knew how Australia very nearly lost their home series to India the last time India visited Australia amd for that, the only reason was the absence of either of these bowlers.
It may take another century before anyone from Australia - or for that matter, else where in the world - to come any where closer!
As a true cricket lover, I have enjoyed watching them! I wish them the Very Best in their 'life after cricket'!
