Hugh Dallas should be hanging his head in shame this morning, or be out drinking with his Celtic buddies, after a series of disgraceful decisions ruined the match between United and Celtic yesterday.

Three times United had STRONG penalty claims turned down, and everyone from commentators to Celtic fans cannot believe that none of them were given. Three decisions!! Then to add insult to injury, the 'unbiased official' awarded a penalty to Celtic!

It’s no secret that this referee has received intimidating threats from sections of the Old Firm support, and one has to believe that this situation is affecting the ageing referee’s performances, as yesterday’s should be investigated by the Fraud Squad.

Take nothing away from Celtic, who were far and away the better team, looking dangerous whenever they went forward – but United looked potent too (at least early on) and when they did get into dangerous areas, decisions by the above named ‘referee’ went against us – not for the first time either this year.

Hugh Dallas should never referee another game at Tannadice again, and his performance yesterday should be the subject of an official investigation.

I hope Ian McCall lodges an official complaint through the official channels – that performance merits it.
