I do believe he is a great player and has great potential, he just really needs to sort his attitude out and become a hard working proffesional. His only downfall was that he thought he was a world beater and he wasn't. I wouldn't want him to upset the teams chemistry either at the moment which I think would be a serious problem if he came back into the squad.
In all honesty, I don't think he is good enough to be in the first choice team, so even if he did show some humility and even if NA and NC allowed him back into the fold, he would only be a bit player. Would he want that and react like a true pro? I think we all know the answer to that... Sell please.
Most people would have got rid of Puncheon for the first reasonable offer..I think Nicola is torturing him.
I do think Puncheon is a very good player, but he has the wrong attitude. He isn't the first player with the wrong attitude, as far as the club he plays for is concerned. There have been plenty, over the years. Off the top of my head, George Best... and all those who thought they were bigger than the club they played for.
