Listening to the Lee Miller interview I think Lennon does regret phasing his desire to be the best in the way he did. Nothing wrong with wanting and saying you want to be the best and McGinn readily acknowledged that. He also spoke highly of Miller's ability and maturity. McGinn revealed how badly he himself had been treated by senior players when called up, Charlie Adam in particular, and gave the impression that he would ensure Miller was not treated in such a bitter, jealous manner.
I thought McGinn spoke well as a captain, supported Miller and said nothing wrong. It's only the media looking for a story and a few on here that seem determined to find fault. Steve Clark also spoke well on the matter and dismissed it as nonsense.
