Steve Lomas hopes the old adage that refereeing decisions even themselves out over the course of the season proves to be true after claiming all the big calls have gone against St Johnstone since he took over as manager.
Lomas replaced Derek McInnes at the helm in November and has guided the Perth club to fourth spot in the Clydesdale Bank Premier League so far and to within touching distance of a Europa League berth.
But he said: "We keep hearing that decisions even themselves up - that old saying that keeps coming out. Well, since I've been in Scotland, we have not had decisions go our way. The key ones are definitely going against us."
He went on: "I keep saying that referees have a really hard job. But that old saying that comes out that decisions even themselves up over the course of the year - not since I've been here.
"So Derek must have had a hell of a lot of decisions going in his favour in the first 12 or 13 games because we ain't seen it. Maybe you can only take it as bad luck. Referees call it as they see it.
"I would never question a referee's integrity. Never. It's a hard enough job. But we definitely feel we are not getting key decisions at the minute and it's hurting us."
Saturday's visit of Dundee United to McDiarmid Park is the first of the post-split fixtures.
While a fan of the concept of the SPL split, Lomas feels aggrieved Saints were handed one less home game than their top six rivals, while having three consecutive away fixtures.
He said: "I think it says a lot about the character of the players that we have had setbacks but we've bounced back. That's football and we get on with it. We have taken it.
"We've had our fair share, we've had the short end of the stick in the split. I'm a fan of it, I think it's great, but we have had the short end of the stick again."
