The Mexican was the difference for United at the Brit.
Ferguson said of Chicharito's first goal at Stoke, a brilliant backwards header: "For a little lad he has terrific spring. He's managed from a standing position to get his head to a knockback from Vida.
"But I'm not surprised, he really can jump. He's got a good instinct of where the goal is and he just guided it in really."
The boss went on to praise the player's off-the-pitch attributes.
"He's got a good attitude, a wonderful demeanour about life, wonderful manners, he speaks the language well, trains really well and he's working on his upper body every morning. He's coming on great."
