GRAEME MURTY believes he has found the answers which will give Rangers a chance of upsetting record odds against Celtic on Sunday.

The interim manager, who is expected after the match at Parkhead to make way for Pedro Caixinha, has been given the unenviable task of trying to prevent a fourth straight derby defeat of the season for the Ibrox club.

Celtic's victories in the subsequent two matches were closer in terms of the results but the champions-elect were by far the better side in both the League Cup semi-final and Hogmanay's meeting at Ibrox.

Murty and his players have been all-but written off in some quarters; however, following successive wins the man still in temporary charge is confident Rangers have it in them to cause what would be a massive upset.

He said: "I’ve got a clear understanding of what it’s going to take and I’ve got a clear understanding of some of the principles that I would like to instil in the players if I was to take charge of the game, and a clear understanding in my mind of what it’s going to take to get a positive result.

"It’s not rocket science, you have to cope with what they are going to bring to the party and it’s down to players supporting one another and actually embracing the challenge and not being fearful.

“These are going to be really big elements, regardless of any tactical changes or formations or anything, it’s about players standing up at Parkhead and that’s going to be vitally important.

“The more I see of this game, the more I’m convinced that we need to embrace more advanced techniques in getting into players’ minds and their mind set and hoping they will be mentally stronger and be better decision makers under pressure, because that is what it comes down to.

“The best players in the world make the best decisions 99 percent of the time and that’s why they are at the top of their profession.”

Rangers supporters remain sore at the memory of the 5-1 humiliation in September, the game which told Scottish football how this campaign would pan out for both sides.

Murty hopes lessons have been learned from all the games, but especially that one, which can be taken into episode four of what will be a six-part Old Firm series.

“As a squad you look at the reasons why, you look at when we’ve had success against them and when we’ve done well, and I’m a big believer in acknowledging what they are good at to prepare fully," said Murty when speaking to Rangers TV.

“So look at what they are good at and say ‘fantastic’, but once you acknowledge it and once you say ‘this is what they are going to try and do and this is where their strengths are’ you then make the players and yourself accountable to what happens after that.

"The game previously at Parkhead isn’t something to be fearful of or to shy away from, it is something to learn from and if you are going to learn the lessons and go and move forward, I think that is really important. I do think, however, that Celtic have changed since then, I think they’ve evolved.

“I think they’ve strengthened in certain areas, they do things slightly differently, so we have to just take what they are going to bring but try and understand that it’s going to be about us and how we manage our expectations of our group.”

There remains a chance that Caixinha could take the team on Sunday, although as the days pass that already unlikely scenario would seem impossible,

“I’ve always said for me to project myself forward into that game (against Celtic])would be arrogant and presumptuous," said Murty who will have had five games as manager after the weekend.

"The closer it comes the more I will have to look at it, but until it happens I’ll just carry on and make sure that the players get what they need, because I’m sure that if I’m in the dugout there will be loads of emotions washing through me.

“But I have to make sure that the players get what they need and when I walk away from this role and I do whatever role I’m going to do, I have to take that away, that the players walk onto the football pitch get what they need 100 percent of the time and I’ve been guilty as a coach of being selfish and getting my frustrations out and you can’t do that."
