Crerand feels Sneijder would be the ideal final addition for this summer's transfer market.
"There's all this talk about United buying Wesley Sneijder and Samir Nasri. I think that would put the icing on the cake if they could buy a top quality midfield player," he told talkSPORT.
"That's not to take anything away from the squad of players they've got, they're a tremendous squad.
"I've never been so sure of United winning a title [than I am now]. Two young kids that have come to the front, Tom Cleverley and Danny Welbeck, are great finds."
