PEDRO Caixinha last night revealed he is compiling a list of the refereeing decisions which are given for and against his team on the eve of the first Old Firm game of the season.

Caixinha, whose side take on Celtic at Ibrox this afternoon, has grown increasingly concerned about the number of bad calls which he believes match officials have made in games involving his team.

He is convinced they currently outweigh the rulings which have gone in his side’s favour – and will speak to SFA head of refereeing John Fleming at the end of the 2017/18 campaign if that is still the case.

“I am not here to point or to criticise the referees,” he said. “Sometimes they have good decisions, other times they have not. As long as by the end and you take the count there is no deficit. So far I think we have a deficit.

“I am working on it. I am going to do like an account list, for and against.

“Normally, when things are regular, by the end everything is balanced. I just want to understand and see how things are going to be.

“The first time I started to do it was in Mexico. Everything is discussed because we want to have a clean and open communication so anything that might happen we need to discuss it and if possible we need to discuss it in private.

“My question is to analyse and to discuss it by the images that are sent to the referees’ committee with our thoughts about it.

“Are we seeing the game and the rules of the game being applied in favour/against/in favour/against?”
