Neville claims Ole Gunnar Solskjaer has a better chance of winning the title with United than Mourinho ever did in his two-and-a-half season at Old Trafford.
He told Sky Sports: "Over the last 12 months, Manchester United have put an incredible run of results together. The points tally has been big, year to year.
"To actually go 20 games away from home needs applauding because it's hard to do that. What do you use to demonstrate teams that have got good character and personality?
"They're good away from home, they're good on set pieces, they look like they want to play with each other.
"I think they've got a far better chance of winning the league in the next two or three years than they were under Jose a couple of years ago.
"I thought it was a strange bunch of lads, they just didn't seem to like each other. They didn't really appeal to me as a fan."
