Neville does tend to go overboard and become a bit of a drama queen, I think he does a good job though, when he first got the Sky gig I was dreading it because of his deep red roots, but he has proven to be quite impartial.
If anything he probably shits on United more than any other team in the Prem and loves City lol. Apart from that is when Ederson nearly got decapitated by Mane and Neville wouldn't shut up about it for the rest of the match saying it was a fair challenge.
