Celtic progress virtually guaranteed after four-goal salvo but Rangers falter
Henrik Larsson opened the scoring and that was followed by goals from Didier Agathe, Stilian Petrov and Chris Sutton to hand the Hoops a massive boost ahead of the return leg of the third round qualifier at Parkhead.
Celtic, playing in their all-black away strip, tried to put MTK Hungaria under pressure straight away and Stilian Petrov had a couple of early chances for the Hoops without really troubling goalkeeper Zoltan Vegh.
