"We're still in a good position when you look at the bigger picture. We haven't lost, we're in good form - we played well at times tonight, controlling the game - and so we go into the next game looking to keep the momentum up."
The momentum is certainly with Dimitar Berbatov at the moment - the Bulgarian put the Reds 1-0 up at Birmingham with his third goal in the space of three days. Carrick just wishes United could have added to his opener and sealed the victory.
"It was a good move and a terrific finish by Berba," said Carrick, recalling the strike on MUTV.
"His confidence in front of goal is very high at the moment and hopefully that continues for a long time. His goal put us in a great position but if we had done better with a couple more opportunities on the counter-attack then we would have been a lot happier.
"That's the hard part to take about their goal going in - the fact that we had managed to get ourselves in front in a tough game."
Carrick denied that playing two matches in just over 48 hours had affected United's players in the final, ultimately costly moments at St Andrew's.
