Celtic boss Gordon Strachan freely admits the Hoops have only themselves to blame for handing the initiative to rival Rangers to clinch the SPL title. The champions have failed to build on an eight-point lead over the Ibrox men at the top of the SPL after a 2-2 draw with Dundee United on January 3 at Parkhead.
"Everyone knows what the situation is," he said.
"We are two points behind, we are looking to win a game and we are looking for help from somewhere else.
"We have nobody to blame bar ourselves. We understand that and we get on with it.
"We would like to have done better, we would rather be a few points ahead but that's the way it is and we are not making any excuses.
"On Sunday, we have one more chance to rectify that and to give it our best shot.
"If we are successful, fair enough, but if we are not then we have had a good bash at it."
