The Scot lit the blue touchpaper for a first-half blitz that stung the Bees and saw Sean Dyche’s men go into the interval with a three-goal cushion.
And despite signs of a revival from the hosts when Alan Judge netted his 11th goal of the season on 57 minutes, Burnley held firm to register a third win on the road in a week.
Arfield said: “I’d say that’s probably the pick of the bunch in my career from a technical point of view. We moved it through the thirds and to cap it off with a nice finish was terrific.
“Joey told me he got clipped so he didn’t see it, but he watched it back in the dressing room as well as his own.
“I think it’s the most fluid we’ve been this season. We had a good win on Tuesday at MK Dons where we were ruthless but in terms of keeping the ball and causing problems that’s the best all season.”
The Clarets have now closed the gap on the automatic promotion places with four wins and a draw in their last five outings.
Goals are now being spread amongst the side, with five goal Arfield feeling his teammates have the ‘confidence and quality’ to make an instant Premier League return.
Reflecting on the second-half, he added: “We played higher up the pitch in the first-half and waited for the mistakes whereas in the second they had a real go.
“That’s what we were expecting and we dropped off a little bit which is something we might need to work on.
“It’s always been our aim and we’ve never hidden away from the fact we want to get back to the Premier League straight away.
“Automatics is the best way and I feel we’ve the confidence and ability to do so – nights like this certainly go a long way.”
