AMSTERDAM, Aug 25 (Reuters) - Serbian international Danko Lazovic struck twice on his debut to inspire PSV Eindhoven to a 5-0 romp over NEC Nijmegen in the Dutch league on Saturday. Lazovic, who joined from Vitesse Arnhem in June, opened the scoring in the sixth minute when goalkeeper Gabor Babos dawdled on the ball. Eric Addo then doubled the home team's lead on the stroke of half-time. The third goal came from Lazovic in the 82nd minute after a fine combination with Otman Bakkal before Brazilian Fagner and Bakkal completed the rout. PSV are joint top with six points from two matches, alongside Vitesse who defeated unlucky AZ Alkmaar 1-0. Alkmaar dominated after Santi Kolk capitalised on good work from Harry Gommans to give hosts Vitesse a 26th-minute lead. Roda JC Kerkrade are third on four points after beating Heracles Almelo 2-1 on Friday. Sparta Rotterdam fought back from 2-0 down at Willem II Tilburg, Darryl Roberts scoring two minutes from time to salvage a 2-2 draw.
