Aussies must wear out Flintoff and play positively: Warne

"With the Ashes up for grabs over the next five days, Australia need to play positive cricket from ball .. if we are to retain the famous little urn," Warne wrote in his column in Daily Telegraph.

"Australia must remain aggressive and try to win the Test match. If Ricky Ponting and the boys take in a conservative approach and just try to bat for long periods at The Oval it could hurt them and they could pay the ultimate price," he wrote.

The legendary leg-spinner also advised the Australians to strategise Flintoff's early fall to improve their chances of winning the series deciding Test match.

"They will also welcome back Andrew Flintoff with open arms, and he will undoubtedly inspire his teammates in his final Test appearance for England.

"Australia have to make sure that Flintoff bowls four or five spells in the first innings. They have to wear him and his knee down, and make him tired," he added.
