Tommy Oar and his FC Utrecht teammates were stunned by little known Luxembourg side Differdange 03 in Europa League qualifying on Thursday.
The Dutch outfit were beaten 2-1 by Differdange at the Stade Josy Barthel despite taking an early lead through Jacob Mulenga.
Differdange's Moroccan striker Omar Er Rafik levelled for the home side prior to the half-hour mark before giving them the lead in the 57th minute and eventual victory.
Australian winger Oar played a full 90 minutes for Utrecht whilst fellow countryman Michael Zullo was an unused sub as Jan Wouters' men prepare to override the one-goal deficit back at the Stadion Galgenwaard next week.
