Michael O'Neill said he hardly ever went to EPL matches as his 3 players that plied their trade there would be in his squad as long as they were upright and breathing, I'm not suggesting just blindly picking players but surely we could come up with a system that gets results and then fit some of our players into it.
We apparently aren't picking certain players due to their work rate, that's fair enough if the manager has insisted that they play in a high tempo manner and they haven't, wonder where Celtic would be this season if he had just discarded all those that weren't playing in that manner for the previous manager.
