Phil Knight, chairman and chief executive of sports merchandising powerhouse Nike, has kept quiet on the details of the £300 million, 13-year contract he has signed with United. But the agreement is so important to the club that Knight --as much as the Irish - might well become United's kingmaker. Without the house of Swoosh, United is £20 million a year poorer - and worth a lot less as an international franchise. Whatever the outcome, United fans should not worry that the club will be short-changed, even if one of the Yankee tightwads does win control. Both Anschutz and Glazer have spent freely in their respective franchises and, like Nike's Knight, they play to win.
