Manchester United duo Anthony Martial and Morgan Schneiderlin missed Monday's (17 October) clash with Liverpool due to injuries suffered in training ahead of kick-off.
Martial, who scored a superb goal prior to the international break against Stoke City, was left out of the match day squad for the drab 0-0 at Anfield.
SFR Sport reported ahead of kick-off the France international would not feature due to a knee injury suffered on Saturday, with the United boss not willing to risk the 20-year-old. The club later confirmed his absence via their official Twitter account.
Schneiderlin was also left out of the match day squad after picking up a knock on Saturday, with Mourinho selecting a midfield trio of Ander Herrera, Marouane Fellaini and Paul Pogba. Herrera provided a superb performance in a deeper midfield role, winning the man of the match award on the night.
While United largely controlled the first half, they failed to carve out any real opportunities to take the lead. In the second half, Zlatan Ibrahimovic passed up their best chance of the game, miscuing his header after a fine delivery from Pogba.
Liverpool, invigorated by the introduction of Adam Lallana of the bench, improved in the second half with Emre Can almost breaking the deadlock, only to be denied by a superb save from David de Gea.
The United goalkeeper was called into action again soon when Philippe Coutinho attempted to find the top corner from 25 yards out, only to deny him with a diving save.
Speaking to Sky Sports after the match, Mourinho said: "It was a difficult game for us and them. I think it was more difficult for them, we kept control of the game for long periods. We started well, in the first half we were completely in control in the second David had two good saves but the game was under control.
"They did really well, we had people who performed in a way where the tactical plan for the team was there. We had a big chance I thought Zlatan would score, but I think we missed a little bit of sharpness through the middle. I was expecting a bit more penetration.
"We did not want to control the ball all of the time. We knew they would press. We know the transition when they lose ball they press high. We had to adapt to the situation, we always thought we would score to win the match but they are a very good team."
