Manchester United manager Erik ten Hag said a change in attitude and spirit from his players was the reason behind a huge 2-1 win over Liverpool.
"We can talk about tactics but it is all about attitude," said Ten Hag.
"I am happy with the performance but we have to bring it every game. Don't just bring it against Liverpool. Every Premier League game is difficult, we need to bring it to every game. It starts, once again, with the spirit."
"Today was really important for us," said Bruno Fernandes, who was made captain in the absence of Maguire.
"We showed the right intensity and more importantly the right character. We got the three points. Scoring first was really important for us, for our confidence.
"It was important for us to take the first step in the league, now we have to carry on."
