text: SOCCER - DISAPPOINTING AJAX SLUMP 2-0 AT HEERENVEEN . AMSTERDAM 1996-08-24 Dutch champions Ajax Amsterdam faltered in their second league match of the season on Saturday losing 2-0 away at Heerenveen . Ajax , who had a dismal series of pre-season results before beating NAC of Breda in their opening game , had the best of an entertaining first half but failed to break the deadlock . Eight minutes after the interval , Heerenveen 's Romeo Wouden broke through the Amsterdam defence , left defender John Veldman standing and curled the ball beyond goalkeeper Edwin van der Sar into the Ajax net . Ajax , without injured defenders Marcio Santos and Winston Bogarde and strikers Jari Litmanen and Marc Overmars , then stepped up the pace and looked certain to equalise . But they left gaps at the back and on 73 minutes Danish striker Jon Dahl Tomasson rushed out of his own half , beat the Ajax defence and lobbed van der Sar . The defeat means Ajax 's main title contenders PSV Eindhoven , who beat the champions 3-0 in the traditional league curtain-raiser , can go three points clear of their rivals if they beat Groningen on Sunday .
