Sydney, Jan 2

Australian captain Ricky Ponting has warned his side against underestimating the unpredictable Pakistan team in the second cricket Test beginning here Sunday.

Australia won the first Test at Melbourne by a convincing 170-run margin, but Ponting knows that Pakistan have the talent to turn the tables on the hosts.

"Teams are probably at their most dangerous when they've come off a heavy loss like last week," Ponting said Saturday. "The challenge for us is to not get carried away with what we've done."

Ponting said that Pakistan are known to come up with gutsy performance with their backs to the wall.

"Pakistan, for as long as I can remember, can be as good as anybody going around and then an over or a couple of overs later, look as ordinary as anybody," he said.

"That's the nature of the way they play their cricket. That's the unpredictability about them, we can't afford to think that things will happen well for us again this week.

"They are already talking up the fact they think they can bounce back quickly. We know what to expect from them, we know they have some very talented players. Last week we had their measure, it's up to us to make sure we start well again."

Ponting asked his bowlers to maintain the standard of the Melbourne performance for the rest of the three-match series.
