Moyes was pleased with the way his side responded after going behind early on, especially after their disappointing Capital One Cup exit at Leeds.
"We played ever so well at times in the first half but it took us 15 minutes to get going as I felt there was a bit of a hangover from the result in midweek," he said.
"But they deserve great credit for going about their job and how well they played.
"It was nearly action every minute: it was great theatre for 30 minutes before half-time and we maybe could have scored more.
"I was clapping at the number of opportunities and chances and you could see how much the crowd are enjoying it so when you drop off (after half-time) it is quite noticeable.
"It is always a dangerous score when you are leading by two because you are worried if you concede one they are back in the game and I think we played like that in the second half."
