Gary Neville is buoyed by the quality of football Manchester United is now producing.

The Red Devils exacted some much-needed revenge on derby rivals Manchester City on Sunday in the form of a 4-2 victory at Old Trafford.

The win was Louis van Gaal's side's sixth on the trot in the Premier League and the manner of the triumph was not lost on former skipper Neville who felt United's past quartet of results have been sublime.

Of the wins over Tottenham, Liverpool, Aston Villa and City, Neville told Sky Sports: "They're getting so confident now. It is a fantastic four performances.

"Against Spurs, you were maybe saying: 'Spurs were poor that day, they were flaky.' So you were thinking: 'Is that the real deal?'

"To go to Anfield and win makes you really sit up, because it's a tough place to play no matter how Liverpool are playing, what point in the season it is, or what point Liverpool or United are in in their development.

"But to come here today, especially after City started well and went a goal up, that's a proper performance."
