This was always likely to be a pivotal week in United's season and, so far, it could not have gone any worse.
But Vidic insists there is no point feeling down about the situation. It is at times like these when United need to show some character.
"We were down after the Bayern game but we cannot afford to be down again," said the Serbian.
"We need to get our heads up and face the facts.
"We have lost two games but we shouldn't feel sorry for ourselves.
"We need to seize the moment and make sure we finish well this season."
