Carroll made his first start for the Reds in their 0-0 home draw with SC Braga and the boss was pleased with the way his £30m signing applied himself.
"He stayed on longer than we hoped he'd have to stay on. Necessity meant he had to stay on the pitch because we needed to score a goal," said Dalglish.
"He has tremendous assets and we need to learn how to get the best out of him. We've also got assets that he has to learn so he can get the best from us.
"Overall we are pleased to see him back on the pitch. We weren't disappointed with his contribution in any way.
"He was a bit unfortunate he didn't score a goal. He had a header in the first half that was just wide and in the second half another one where Dirk Kuyt got in the way.
"It was his first start and he can be very pleased with how he played."
