Vidic was impressive in victory at Stoke City on Sunday.
"Stoke is always a difficult place to go to but we fought for every ball, played some good football and, in the end, I think we deserved to win," he told MUTV. "It was physical. You know they're going to get the ball to the forwards, they're good at set-pieces, they're going to challenge defenders.
"Now it's West Ham and we have to play well again. They play in a similar style to Stoke - we're going to have long balls and set-pieces to deal with."
