HE does know quite a lot to be fair though as is evident in his analysis of the game and is obviously helped by the fact he has coaching badges and played his whole career at one of the biggest clubs in the world.
I think a few people are getting caught up a bit to much about it, he did overreact to de Gea and he probably is overly complimentary on English players but so is everyone in the English media. If you listen to Spanish commentary I'd imagine people such as Mascherano might come in for more criticism than the likes of Xavi if they both made the same mistake, it's just the way things tend to work.
I don't think it's anything to do with just Neville and his England role I've seen him be critical of English players but what does he get out of it? People are making out he turned around and said de Gea is shit, he just said he can improve on certain areas which he can. I agree it was slightly OTT in the aftermath of the game but on the Monday I thought he was alright about it.
I've never understood all the comparisons to Hart either like they're the only 2 keepers in the league either, Hart does make mistakes but in fairness he was very very good last year.
