Ireland captain Brian O'Driscoll is looking forward to testing himself against Australia counterpart Stirling Mortlock in Melbourne at the weekend.

 

The opposing skippers will wear the No. 13 jerseys in the one-off Test on Saturday in what is bound to be a pivotal midfield match-up.

 

And although O'Driscoll admitted Mortlock was one of the best players in the world, the 29-year-old said he will look forward to find weakness he can exploit.
