Juan Mata put the hosts into an early lead during Sunday's clash, but Chelsea were able to take advantage of a mistake from David de Gea to secure an important point in the battle for fourth.
Chelsea's destiny is now in their own hands heading into the final two games of the Premier League season, but Sarri has insisted that his side must take maximum points to confirm their return to the Champions League.
"We need two wins. With two wins we are sure. With four points, I don’t know, it depends on goal difference." Sarri said, via the club website.
The game itself was a difficult one to assess for Chelsea as, although the result was a positive one, the Blues' weren't at their best. Sarri acknowledged this, saying:
"But to play here in Manchester against United is very difficult for every team. They played very well in the first 20, 25 minutes.
"We were in trouble because we didn’t have the right distance between the striker and the midfielders. The ball was always free, and they are very dangerous when they can attack space behind the line.
"We were better in the last part of the first half and then the second half. We didn’t risk anything in the second half, only the corner in the last five minutes. We played very well in the second half."
