He added that the star was being groomed to become the World Champion somewhere down the line. However, Russo believes that it would not be a great idea."First of all, I saw it [Sami Zayn becoming the United States Champion] a mile away. Second, they're grooming him to put the big title on him; that's what they're going to do, and there is no casual fan on this planet that is ever going to get along with that company if Sami Zayn is your World Heavyweight Champion, not one casual fan on this planet," Russo said.Before his sudden move to Friday Night SmackDown, Zayn had his sights set on the World Heavyweight Championship on the red brand. However, he turned his attention towards the United States Championship after showing up on the blue brand in Quebec, Canada, as Solo Sikoa's mystery opponent and defeating him despite interference from other members of the MFT.It will be interesting to see if the heel faction tries to take the title off The Great Liberator.
