I've read through all the post since the game and no one has accused him of being racist, that you've just made up.
I've seen implication of him being xenophobic in his footy and that itself isn't far from the truth. He has his English bias while he rip into foreigners. How many time have you heard Neville go over the top on Maguire who had cost us goals 2 or 3 games in a row? Never. This tells you everything.
Heck ask yourself this question: How many times has Neville gone on some embarrassing rant when it comes to Pogba or a Martial or DeGea(When he just joined us)? Quite a few times but you'd never hear him go on embarrassing rants on any English player, not even Lingard. The fact the likes of Pogba, Martial, DeGea have gotten far worse criticism compared even to the likes of Lingard is another telling truth about Neville and his English bias. like someone mentioned, he is an Englander.
