The Red Devils drew with already-relegated Huddersfield on Sunday and will now be playing Europa League football next season.
Ole Gunnar Solskjaer’s side took the lead through Scott McTominay, but were pegged back by Isaac Mbenza’s second-half strike.
The point left Solskjaer’s side four points behind fourth-placed Tottenham with one game left, with a sixth-place finish behind Arsenal appearing likely.
And Neville, who won eight Premier League titles with United, slammed the current crop of players’ lack of team spirit.
He told Sky Sports: “This is Huddersfield Town who have struggled all season. You watch them, they haven’t got the quality, but I like watching them a lot more than the ones in the red shirts, to be honest.
“At least you can identify with them. There’s nothing I like about this United team at all.
“It’s just awful. Look at them. They’re the most despondent group of people.
“As a manager, you want to like your team. I look at Ole Gunnar Solskjaer, I can’t imagine he’s down there thinking he likes watching this lot – I don’t.”
Neville went on to compare United to the Tottenham team which Mauricio Pochettino inherited in 2014.
