Vidic says United will always win and lose as a team.
He told manutd.com: "If we want to win the title we have to perform together as a team and take responsibility as a team, not as individuals.
"We shouldn't point at the finger at anyone because we play as a team. This is the most important thing to remember.
"It's about performing in training and showing that you want to work hard, you want to improve and you want to win. This is what all the players are trying to do."
