The 32-year-old was impressive as United created a number of chances in the second half and said that, despite taking all three points, the squad is still yet to reach its full potential.
Speaking to MUTV, Carrick said: "I thought we did more than enough to win the game, and should have won it by more. It would be nice to see some more go in to make it a bit more comfortable; it was a similar scenario at the weekend against Southampton, so we were conscious of a goal in the last minute. But, we've seen the game out very well tonight and, in the end, we've taken away a win.
"I think we can improve on a lot of things, there's still a way to go until we're really at our best, but we haven't been playing that badly. Things haven't been going so well for us in terms of results, we'd love to score more goals, but the good thing is that we are creating that chances. We're making the opportunities for ourselves, and I'm sure they will start flying in soon."
