Terriers boss David Wagner told HTTV: "We decided to play in a shape where we overloaded the wings and stopped the inside past. We've done that well.
“We knew they weren't the strongest at defending set-plays, so credit to the coaching staff for working on that.
"I am very pleased with the attitude and that performance. The biggest trait is the togetherness and desire to work for each other."
Wagner ereserved praise for Billing and praised his players' work ethic.
"We had good deliveries from set-plays; I am pleased for Phil (Billing). He has performed, like the whole team, on a very high level in terms of organisation and communication.
"It would have been good to have defended the cross for their goal better and better marking of Calvert-Lewin. We shouldn't forget it was Everton away though, and we limited them to only a few chances.
"I've seen this work ethic before. These players will always give absolutely everything. We still need to improve and grow, especially in the final third. The Terrier spirit is something that every supporter can be proud of."
