Anthony Ralston says Celtic are trying to remove the 'craziness' of games with Rangers as they close in on the Premiership title.
The Hoops face their Glasgow rivals for the fifth and final time this season on Sunday in a match that will all but certainly decide where this year's top spot goes to.
A victory for Celtic would put them nine points clear with three games to go, whereas a Light Blues victory throws them back into the mix, albeit still needing to make up a three-point gap.
