But he insists Manchester City were worthy winners.
Neville told Sky Sports: "In terms of the season it's very early days, it's so early. For Pep Guardiola and City it's a big day, to come and win here against a Jose Mourinho team is tough. He doesn't lose many games at home, and it's a big, big moment.
"Jose Mourinho will be dented tonight, damaged slightly; he's a man of great pride, but they'll respond, it's still early days, and it doesn't tell us about the league title and where it's going.
"Ultimately it means City have bragging rights this week, and that I won't appear in Manchester as much as I would have done if United had won!"
