Willie Collum has been appointed referee for this weekend’s Premiership match between Celtic and Aberdeen.
Former Fifa referee Erman Toroglu branded Collum the worst official in the Champions League after he produced eight yellow cards in Galatasaray’s 2-1 win against Benfica last week.
He said: “I have seen some bad refereeing performances in the Champions League, but nothing compared to the Scotsman Collum. He wasn’t anti-Galatasaray or anti-Benfica – he was just very bad. He doesn’t seem to understand refereeing. He should stick to wearing a kilt rather than a referee’s uniform.”
Collum has produced 57 yellow cards and four reds in 16 games this season.
Don Robertson will take charge of Ross County’s match against bottom of the table Dundee United at Tannadice, while Brian Colvin will referee Caley Thistle’s home match against Dundee.
