Tonight's previews:

Aussie - Italy

Most would expect an Italian win given their personnel, their ranking and their history. They have won the world cup on more than one occasion and seem to be a constant figure in the round of 16. Aussie on the other hand are in their second world cup and in the round of 16 for the first time. They do have a good squad though and Guus Hiddink is a wily campaigner. However I expect it to be close and I really think there is a potential for an upset on the cards. I hope so anyway!

On the injury front, Kewell is struggling with an injury and may not start, Nesta is ruled out.

Also: can Viduka finally find his goalscoring form, he has been playing well as the lone striker but would no doubt love a goal.

Swiss - Ukraine:

Should be tight. It's the clash of Frei vs Shevchenko, both renowned goalscorers. Switzerland haven't conceded a goal yet at WC 06 but they are without Senderos. Ukraine have been criticised at times but this is the moment for Voronin and Kalinichenko to step up, they have looked dangerous at times, they need to do so again. They do have 2 defenders suspended however.

One of the four second round matches has gone to extra time. None of them have reached penalties. Is tonight the night where all this changes? Or will the trend continue? Tune in and find out!
