Here's what we learned from the Goodison Park encounter. Energetic on the flanks and clinical up front, the Blues looked a cut above their sorry opponents on Wednesday night. When it comes to tactics and substitutions we can communicate when he is up there. Calvert-Lewin's effort after Lennon's neat backheel on the edge of the area was well saved by Lossl before the Danish goalkeeper was beaten again in the 73rd minute.
Internationally, Mooy has represented Australia since Under-20 level and made his senior debut on 7December 2012 against Guam, scoring a free-kick in the 9-0 win.
Booked for cynical trip on Lennon after former England man got wrong side of the left back.
Just over a week from now, Everton play Jurgen Klopp's high-energy Liverpool side.
Huddersfield come into the game at Goodison off the back of three losses on the bounce.
Christopher Schindler - 7/10: This was a fairly average performance for the German defender, he wasn't spectacular but at the same time didn't make any stand-out mistakes.
Everton made sure of the points 16 minutes from time.
Tom Ince's fumbled corner at the other end prompted a goalmouth scramble, but that was the closest Huddersfield got to testing Jordan Pickford in a poor first half. Everton were at pains to ensure they were not caught with too many men ahead of the ball. Caught in possession for Everton's second goal.
After being given a warm welcome from the home fans, new manager Allardyce took his seat, hoping to see further signs of Everton's rejuvenation following their crushing 4-0 defeat of West Ham United in midweek. This was all cute passes, with not a long ball or a set-piece in sight. Managed a couple of last-ditch interceptions as the hosts threatened to break. I don't know the players we will get yet. Lee could also be seen offering regular advice to Jonjoe Kenny, Everton's young right back - the recipient of an early booking for chopping down Elias Kachunga. Tried in vain to keep out Calvert-Lewin's shot for second goal.
Frequently, Sammy Lee would join him, leaping from the dugout to contest decisions with David Wagner, the Huddersfield manager.
He grasped it with both hands here, netting the game-ending second after a powerful run forward.
If anything, it encouraged an improvement from Huddersfield, who suddenly started to enjoy some command.
