After the turkey game
"I spoke to Martin O Neill and contrary to his recent comments, I never asked for a regular starting position."I did, however, disagree with certain aspects which out of respect to Martin and the national team will remain private."
That does sound a bit precious to me and I'd have little doubt that he would have been capped a number of times had he been determined to play and not put all his chips on those certain aspects which he had a disagreement with. At a guess I'd say the disagreement possibly had to do with making himself available for friendlies eg USA trip.
