Pakistan captain Younis Khan today said his team will play aggressively against Australia in the upcoming one-day series in Dubai and Abu Dhabi and the matches would be the start of their preparation for 2011 World Cup.

"We need to start playing with a positive and aggressive mindset and develop and retain that mindset for the World Cup. I see the Australia series as the start of our process to build a strong one-day outfit. Even if we lose we would have gained a lot by playing a tough series," he said.
