Manager Louis van Gaal believes Manchester United can still aim to win the Premier League title.
With eight games left, the Red Devils trail leaders Chelsea by eight points with the Blues having a game in hand to extend their lead to eleven points.
But the Dutchman will continue to believe as long as it is "mathematically" possible.
"Mathematically, we can still do it," van Gaal said on Friday.
Meanwhile, the 63-year-old was full of praise for midfielder Marouane Fellaini ahead of tomorrow's home game against Aston Villa.
"When he is playing like he is playing now, I cannot change him," the United boss said.
"From the first training session, he did what I asked of him. I said 'you have to do this, or do this differently' and he was open and wanted to perform that, I'm not surprised [by his performances].
"He's had an unlucky season because he was injured and ill a lot of times, but when he's been fit he's always played for me, more or less.
"I was looking for balance in the team, and he can bring that."
