United were 37 points behind the Reds in the table before the Premier League was suspended indefinitely due to the coronavirus epidemic and placed fifth.
Jurgen Klopp, on the other hand, was 25 points ahead of second-placed Manchester City and just two wins from winning his first title in 30 years.
But despite the huge gap, Neville thinks United have a chance to mount a title bid next season.
“United have struggled to keep prices and wages low, but they will be very well placed to keep their cool this summer,” he told the Sky Sports Football Show.
“It will be really important, they had found a shape before that and the glass seemed half full than half empty and 30 points or whatever off Liverpool.
“I’m starting to believe that United could challenge next season. “
Before adding: “They have to add three of the four quality players to this and United will be able to capitalize on the market this summer to do business. “
