Think it was Anderlecht ...
We were similarly subject to some dubious refereeing in the second leg of a Europa tie against Atleti in the Martin O'Neil years ... denied 3 stonewall penalties for fouls on Muzzy Izzet before the ref truly nailed his colours to the mast by giving Garry Parker a red card for taking a free kick 'too early' ... kid you not...
Another one to look out for, if you can get the footage, is the second leg of our semi against Roma in the Europy Conference last season ... we had a corner in the first 10 mins .. as it comes over Chris Smalling, not once looking at the flight of the ball, wrestles Wesley Fofana to the deck ... our players went nuts at the ref and there was, supposedly, VAR in operation ... no check no nothing ... one of the commentators made a comment along the lines of "... well that's quite incredible, in fact, unbelievable, what is going on?" ...
Dodgy ****ers those European teams
