The Clarets won 5-1 on Saturday, with veteran Ashley Barnes scoring twice.
Parker said afterwards: “Really pleased overall. First and foremost, I think we’ve seen it over many years in the FA Cup, it’s not always easy. Not against a team that come here going for play-off spots and have had a real good season to date.
“I thought we approached the game incredibly well. Our general demeanour, our approach towards the game was spot on. I thought we showed some real quality, which was very pleasing. We scored some good goals and overall, a really good performance and one we can build on.”
On the performance, Parker also stated: “I was very impressed. I know we always preach about it and it’s not preaching, its facts, that we’ve got a really tight group here. A group that are really together and work tirelessly, then when they get their opportunity, they take it.
“We needed to freshen things up today, after a lot of games over this Christmas period. I thought the boys came in and applied themselves superbly well and gave food for thought really in terms of their general performance.
“The boys coming in, Jaydon Banel scoring his first goal, was really, really pleasing. I’m really pleased with that.”
