The game in question was against Kilmarnock the week before Christmas. Most fans were left baffled by his performance and he received a lot of criticism in the press. David Fernandez moaned about the lack of protection he was given, although most Saints fans think the Spaniard was lucky not to be sent off.
The other game of ours Mr O'Reilly has done this season was when we dished out a 7-0 hammering to Dumbarton. In fact, that's the only other Saints game he's done - and he hasn't done any matches involving Dundee United!
So, it seems he's a pretty inexperienced official - as was proven by his display at Rugby Park. He's only sent off one player so far this season, but has done just a handful of SPL matches in his career. Saturday could be interesting!
