place finish at the Australian Open has given Tiger Woods a timely boost before this week's Presidents Cup and gone some way to validating United States captain Fred Couples's decision to pick the fallen former world No. 1. The 14-time major winner will continue to search for his old form in front of a bumper crowd at Royal Melbourne Golf Club after a tumultuous period blighted by injuries and personal problems. International team captain Greg Norman has demanded his players shelve tour friendships and seek to emulate the killer instinct Woods showed in his pomp. “Tiger is very much that way when he walks on there. He kinds of says, ‘I'm here to beat you',” said Norman, who has questioned Woods' selection and ability to win another major in the lead-up to Melbourne. “That resonates all the way through. I was the same way. You walk into the locker room at the start of a round. ‘I'm here but don't mess with me today. ‘I want to go to the first tee and beat you'.” Woods has proved a major Presidents Cup headache Norman, who stood powerless as the American won his matches 5-0 in a dominant 2009 win at the last edition in San Francisco. Norman has called on the local crowds to be his team's “extra” team member.
