Agreed. He is 100% correct though to be angry. Had a better keeper been brought in to take his place and it was laid out, that's fair enough.
Murray went on record after the Annan game after which Langfield made his debut and publically declared that Ridgers is still first choice. Now by that point he must surely have had in his head that Langfield would be the better option for Cappielow and if he performed there, would subsequently keep his place. So why declare to a national press outlet that the guy who you've dropped will be first choice going forward if you've no intent to even play him again?!
So many things not adding up in terms of Murray and his style. He's also gone public several weeks back and claimed that Cameron Howieson isn't a left winger (he isn't).....yet played him on the left against Raith Rovers. It's completely baffling.
