The Blues are nine points adrift of leaders Manchester City and four behind second-placed United after 10 games while they are also struggling for consistency on their return to Europe.

United boss Jose Mourinho will relish inflicting a heavy blow on his former club after Chelsea beat his United side twice at Stamford Bridge last term, and he will have former Blues stars Nemanja Matic, Romelu Lukaku and Juan Mata in the side, but Courtois says it is time for the west Londoners to focus

"This is a must-win game," Courtois said. "Manchester City are already nine points ahead of us, Manchester United four and Tottenham one.

"We must win games like these to remain at the top and close to the other ones. We will try to get the three points and will give our lives for it on Sunday."
