Wayne Rooney: "One bad game and everything could fall and so we go out and play each game with a positive attitude.
"We have to stay focused. We have to make sure we keep doing our job and keep our concentration.
"To lose the league in the last second (last season) was a bad feeling.
"But when you are at a club like United, you have to be full of motivation and desire to win every year.
"That comes from the manager and all the players are aware of it.
"The club and the players have to be full of that desire. That's why the club has been so successful."
