A second-half goal from Adam Gyurcso condemned TNS to a 1-0 home defeat in their Champions League qualifier with Videoton.
The Welsh side held their own in the second qualifying round first leg, but were undone 13 minutes from time.
Hungarian outfit Videoton will now fancy their chances of progressing through when the sides play out the second leg in a week's time.
TNS' position is a better one than that of Crusaders, though.
The Northern Irish side were hammered 4-1 away to Albanian club Skenderbeu.
Bakary Nimanga got the home side going (15) before veteran Hamdi Salihi added a second (34).
Jordan Owens pulled a goal back three minutes after the half-time break, but Bernard Berisha made it three and Salihi made it two for the night.
