The Blues went into today’s clash at Old Trafford knowing defeat would see them lose crucial ground in the race to finish in the top four.
Sarri’s side were also aware a win would all-but secure their Champions League status for next season due to Arsenal’s 3-0 defeat at the King Power Stadium earlier today.
The Chelsea boss was asked about how crucial today’s clash with United was but seemed to be more concerned with the remaining two league games that will follow.
“It’s a very important match for us of course but we know very well that we need to win two matches in the last three,” he told Sky Sports.
“So today is very important but we have to think towards the other two matches also.
“In this moment of the season, an English team involved in a European competition is very tired.”
But even though Sarri already has one eye on the upcoming clashes against Watford and Leicester, Chelsea fans will be happy to hear he wasn’t prepared to play for a draw this afternoon.

Chelsea have been buoyed by some positive injury news this week.
And Sarri went on to explain the situation with returning stars Antonio Rudiger and N’Golo Kante.
“Rudiger is very well, he had training with the team all week,” he added.
“And Kante is better, starting [training] from yesterday.
“Not very, very good but better.”
Chelsea will have to divert their attention away from the Premier League in the coming days as they prepare for the Europa League semi-final with Frankfurt.
Sarri’s side travel to Germany for the first-leg on Thursday.
