Manchester United manager David Moyes says he is encouraged at how his side have bounced back from their derby drubbing by Manchester City to knock Liverpool out of the League Cup.
Sunday's abject 4-1 defeat at the Etihad Stadium left United five points off the pace in the Premier League, but they showed fresh signs of life in an impressive 1-0 win over Liverpool at Old Trafford.
"What was important was that the whole club showed that we were hurt by the game on Sunday," Moyes said after a victory that set up a fourth-round tie with Norwich City.
"We didn't perform to our levels. And they've gone out and the players have done a great job to get us a big result, so I'm really pleased with them.
"We know we have to improve. I'm getting to know them. They're a really good team.
"They won the Premiership last year. But we need to make sure that we're looking to improve as well."
Javier Hernandez scored the game's only goal, stealing away from Jose Enrique to convert a Wayne Rooney corner from close range in the 46th minute of an engaging cup tie.
Hernandez's goal eclipsed the return of Liverpool striker Luis Suarez, who was making his comeback after serving a 10-game suspension for biting Chelsea's Branislav Ivanovic in a league match in April.
The Uruguayan played for the full 90 minutes and almost claimed an equaliser with 18 minutes to play, only for his free kick to flick off the United wall and crash against the crossbar.
"Considering he's been out for such a long time, he ran himself into the ground and you could see he was always a threat," Liverpool manager Brendan Rodgers said.
"He put defenders on the back foot, he had a couple of wee twists and turns. And, obviously, as he goes on he'll get sharper, but overall he can be really pleased and I was really happy for him."
