United are 10 points behind leaders Manchester City with thirteen games remaining in the season.
"Every game is a final now," United midfielder Matic told Sky Sports News. "We've dropped some points where we should win so you go into the big games with more pressure and then you have to win.
"I think the next few weeks are going to be decisive in the title race. We will either be there in the fight, or it's going to be difficult because if we drop some points in the next few games, then it's going to be hard to catch Man City.
"But that's why we are here. We are positive, we're going to do our best to win. The next game is the most important and then we will be focused on Man City."
