Striker also thankful team-mates have signed new contracts
Sir Alex Ferguson's side threw away a one-goal advantage at Stamford Bridge on Tuesday, but with Arsenal drawing at home to Sunderland, United now have the chance to cement their place at the top of the Premier League.
Rooney praised United's performance against Chelsea, but the striker maintained that the Red Devils will be detrermined to bounce back from their second league defeat of the season.
"I thought we played well at Chelsea," Rooney told reporters.
"I didn’t think we deserved to lose the game and to concede the winning goal the way we did was disappointing.
"But we have to move on from that now and try to get three points at Liverpool.
"You can’t change the Chelsea result so we have to concentrate and focus on what we are going to do this weekend at Anfield.
"We’ve had to work on a few things in training and we’ll make sure we get it right.”
Having dramatically re-signed for the Red Devils after earlier requesting a transfer, Rooney was naturally glad influential team-mates Darren Fletcher and Michael Carrick had also chosen recently to stay at the club.
“It’s great news," the £200,000-per-week forward said.
"They have been great players for the team and have been very consistent for us over the last few years.
"It is always nice to see players sign new contracts because it’s a big boost for the team.
"It’s great to see all the lads sign new deals but unfortunately [goalkeeper] Edwin [van der Sar] hasn't.
"We would like him to sign a new deal but obviously he has made his decision and we respect that.”
