A more realistic target for United is Gyokeres, who played for Amorim at Sporting CP and has been linked with a reunion in England. But Sheringham doesn't believe his old club should splash the cash on the Sweden international.
"I don't think it's imperative for United to move for Viktor Gyokeres at the moment when you've got [Rasmus] Hojlund. I think there's other areas he would prefer to nail down," the 58-year-old added. "I think the club need a left-back. Shaw's struggling with his injuries. He seems to get one after another, and you can’t pin your hopes on someone like that.
"Another really good midfield player would be great, so I think there are other players and other areas to strengthen that are more important to him than buying another centre forward. As I say, Hojlund is showing good stuff."
