Sir Alex Ferguson has warned his players their planned visit to Chester Races on Wednesday will be scrapped should their performance not come up to scratch.
Vidic though insists there will not be an issue: "Motivation won't be a problem for us,. We are motivated every time we step out at Old Trafford.
"When we go into the games we have a mentality to win which is not going to change against Chelsea or anyone else.
"The only difference is we are relaxed. We are not chasing points for the trophy. That means we can play without pressure and actually enjoy the game. We want to finish in a good style."
