Messi is set to miss the next seven-to-eight weeks after suffering a tear in the internal collateral ligament of his left knee in Barcelona's 2-1 win over Las Palmas on Saturday.
"For years I've known Leo and I have no doubt that he will be ready in the shortest possible time of the injury, perhaps before that period of six-to-eight weeks," Villani was quoted as saying by ole.com on Sunday.
