“We've just got to apologise to the fans and we've got a tough one coming up on Wednesday with the Manchester derby,” Young told Stewart Gardner after Sunday's game.
“We know how important that's going to be. If you can't get yourselves up for the Manchester derby, there's something wrong.
“I've got confidence that we're going to be ready for Wednesday. It's a disappointing day today but we've got to dust ourselves down fairly quickly and go again this week.”
The Reds are sixth in the Premier League and still have an outside chance of qualifying for next season's Champions League.
