Peter Roebuck writes in the Sydney Morning Herald that Australia's struggles in 50-over cricket means their squad needs a radical overhaul, beginning with changes for Friday's final ODI in South Africa and then in the UAE against Pakistan.

Of course, the reconstruction will be confused by the inclusion of old stagers desperate to prove their fitness and relevance before the winter parties are chosen. So be it. The selectors were in a pickle. They could not very well choose a 20-over world cup team or an Ashes touring team on a wing and a prayer. Accordingly, they included serious candidates recovering from long-term injuries in their squad for these 50-over contests. Players with the records of Brett Lee, Stuart Clark, Andrew Symonds and even Shane Watson cannot lightly be discarded. Plain and simple, it is a trial run. Once the winter campaigns have been completed, the 50-over team will need to move along towards the 2011 World Cup.
