Scott McDonald on the biggest stage this week.

Forget John Aloisi, Mark Viduka for the World Cup Finals in 2010.

We need new blood to step up. Celtic's Scott McDonald could be the man.

He's playing Champions League. The only other Aussie playing is Harry Kewell, and occasionally Zeljko Kalac.

Scott McDonald has already scored in European away games and against the AC Milan, the Champions of Europe.

And on Wednesday you can catch Scott and Celtic in the vital Champions League knockout qualifier away to AC Milan on SBS 6:30am.

Is McDonald good enough to lead the line for Australia's World Cup campaign?

We'll get a fair idea on Wednesday, that is of course, should Scott play.
