Tevez scored two goals for United in the first-half of the game.
“It was a superb performance from Carlos Tevez,” Sir Alex told MUTV. “He was like a jack-in-the-box all day and he showed great energy, getting on the ball and showing great movement.
“His second goal, in particular, was fantastic.”
Wayne Rooney scored the third goal, while Park scored the fourth goal for United.
“Wayne was marvellous today,” Fergie said. “He played last Wednesday and he’s only just come back from a hamstring injury. I didn’t want to take any chances because we need him for Wednesday against Inter Milan. That’s why I took him off.
“Right from the word go all the players played with great energy and enjoyment. They went out to enjoy themselves and were backed by a fantastic support.”
