“They can play some incredible cricket, as they have in times I’ve played against them, but they also can self-destruct quite quickly as well,” Watson told reporters at the Adelaide Oval on Tuesday.
“That’s the reason why Pakistan are so dangerous especially in a knock-out game like this quarter-final.
“They have certainly got some match-winners. Once this Pakistan team gets on a roll, they are able to use that momentum to be able to shut down teams very quickly.”
Watson, at 33 one of the senior-most Australian players, hoped his team can see off Pakistan in front of their home supporters and move into the semi-final against either defending champions India or Bangladesh in Sydney on March 26.
“We know this is a danger game for us because they (Pakistan) can come on and just turn it on like they have throughout the times I’ve played them in the past.
“We know we have to be at our absolute best and not give them a chance to be able to get that momentum. We know if they’re able to get that they can run away with it very quickly.”
The unpredictable Pakistanis bounced back after losing the first two games against India and the West Indies in the league to win the next four.
Pakistan, champions in 1992 when the World Cup was last played Down Under, beat Australia by four wickets in Colombo during the last edition in 2011, a match Watson did not want to be reminded of.
“I try to forget that one because we lost it,” he said.
“We knew that was a really important game because if we lost against them we were going to have to play India in the quarter-final, which we knew was going to be a big challenge on their home turf.
“And it worked out that way. I’ve got some good memories but also some bad memories that I try to forget as quick as I can. That was one.
