Leaders Liverpool are currently two points clear of City.
"A few weeks ago, I said that by this stage we'd know who's going to win the Premier League because Man City and Liverpool would be dropping points," he told Paddy Power.
Ince continued: “But, the fact is, neither of them are. In 1993 when I won the league with Man United, there were defining moments in that season.
“The Fergie Time win over Sheffield Wednesday for example, we knew then that the title was ours.
“I sense that now with Liverpool. They're not absolutely blowing teams away, they're just having defining moments and decisions on their side."
