Patrice Evra admits Manchester United must take the Premier League title if they are to avoid writing off the 2011/12 campaign as 'a really bad season'.
The Red Devils have disappointed in cup competitions this term, with elimination from the Europa League on Thursday compounding their misery.
All of their attention must now be focused on the defence of their domestic crown, with there only one piece of silverware left for them to play for.
Evra is aware that ending the season empty-handed would be considered a failure, with it imperative that a club of United's stature pick up trophies on a regular basis.
"A big club like Manchester United should be able to compete in every competition. But now we have no choice, we have to focus on the league," the French full-back told the club's official website.
"We have to win the league to save our season. If we don't win the league, it will have been a really bad season."
Despite seeing United slip out of Europe in midweek, Evra is convinced their continental failings will not be allowed to impact on their league efforts.
"I'm not worried about the league because we are playing well and now we are top, in front of Manchester City," he added
"After tonight we go home and rest, then focus on Wolves (on Sunday) because it's a big game, a massive game and we have to make sure we win."
Evra is at a loss to explain United's uncharacteristic struggles in Europe this season, but is refusing to dwell too long on the events of the past.
"We didn't start well in Europe this year - maybe we were too confident at the beginning of the Champions League - and this is the end now," he said.
"We are out again and we have to be honest with ourselves, we don't deserve to be in the Champions League or the Europa League.
"We haven't played in Europe this season with the same desire that we have in the league.
"We can see the difference in the league - we are top, and we are more focused on the league, we have to tell the truth. I don't know why that is. If I knew the answer, it wouldn't have happened. But it's a bad year in Europe for Manchester United. That's it."
