Chelsea, who are tied at 84 points with United, face Bolton on Sunday, knowing that a victory won't help them if the Red Devils won at Wigan.
United will be automatically announced champions as they boast a better goal difference, but Grant does not concur.
"We've won games 6-0, 6-1, 4-0 and 3-0 this season. When you miss so many players, the first target is to win games, especially in the beginning," said the Israeli.
"I must admit that United have played very good football. They think this is the best season since Sir Alex Ferguson came.
"But I prefer the system in Italy. You play a play-off if you're level and it is decided on that.
"I have interest now to say that. But I like it anyway. Sometimes, you score more goals against weaker teams. If you have the same points, you are at the same level."
Apart from their domestic challenge, United and Chelsea will lock horns later this month for the final of the UEFA Champions League in Moscow.
