Former United skipper, Neville, claims the current crop have not yet reached their potential but should be ranked alongside squads from 1994, 1999 - the treble-winners - and 2008.
"When you're at Manchester United and you've had a manager who has built four great teams - '94, '99, 2008 and you can now argue this one that has won the league - people are always going to compare teams," he told manutd.com.
"The most important thing to say about this team is it's on an upward curve.
"You've got players like (David) De Gea, Rafael, (Jonny) Evans, (Chris) Smalling, (Phil) Jones, (Tom) Cleverley, (Danny) Welbeck and (Javier) Hernandez, to name eight players, who are still young and haven't reached anywhere near their peak.
"You've also got a mix of players in the middle who are at their peak, then you've got the experienced lads at the other end.
"This team has still not reached its potential. I'm sure there will be additions to the squad this summer so you're talking about a team on the up."
