The Toffees opened the scoring through Gylfi Sigurdsson after 28 minutes before Dominic Calvert Lewin's second-half double put the game out of reach. Will Vaulks bagged a late consolation goal for the visitors.
"The manager knows what he wants, he knows his game plan," said Calvert-Lewin. "He definitely works you hard on the training ground and gets you all at it. We've got a lot of belief in what we do. We want to get the ball down and play attacking, positive football. I think we did that tonight but we also want to be patient and enjoy the ball a lot more.
"There's definitely a new buzz around Goodison. There's a good vibe, all the players feel it. We're keeping the football a lot better and the crowd are feeding off that.
"There's a clear game plan and it's to create creative, attacking football and to enjoy how we play. We did that tonight and I think we'll continue to do it going forward. The more work we do - the manager believes it, we believe it - we'll only get better."
