Alex Iwobi admitted he thought he had bagged a debut goal for Everton - but says the Blues will not dwell on their first defeat of the season.
Deadline-day arrival Iwobi produced an encouraging late cameo after replacing Gylfi Sigurdsson on the hour mark with Marco Silva's men trailing to Wesley's 21st-minute strike, an opener that came very much against the run of play.
Having seen a goalbound shot charged down shortly after his introduction, Iwobi then latched on to Michael Keane's nod down, only to see his low left-footed effort cannon off the foot of Tom Heaton's post.
Substitute Anwar El Ghazi was played in by John McGinn to double Villa's advantage late in injury-time.
Everton headed to Villa Park looking to extend a run that had seen them keep 10 clean sheets in their last 13 appearances and record three consecutive shutouts from the start of the season for the first time since 1912.
However, despite boasting 65 per cent possession in the Midlands, the Blues couldn't build on last weekend's 1-0 home win over Watford.
"It's not the result we want on the back of the home victory we've just had," said Iwobi. "We're disappointed but we're not going to dwell on this.
"I felt sharp to be fair, I felt good. But it would have been a better debut if we'd won.
"I had two chances. After the first one that got blocked I thought maybe if I keep going I'll get another... and I was able to do that.
"When I struck it with my left foot I thought it was going in but I saw it come off the post and I was disappointed.
"You can see we are able to create a lot of chances, not just when I came on but even before that.
"We have a lot of attacking players who are able to bring quality and, hopefully, I'm able to add to that as well."
Iwobi's 30 minutes on the pitch also offered a first glimpse of a fledgling understanding with fellow offensive summer arrival Moise Kean, as well as left-back Lucas Digne.
And the 23-year-old says he will keep working hard to get accustomed to his new Blues colleagues with a Carabao Cup visit to League One high-flyers Lincoln City to come on Tuesday before the visit of Wolverhampton Wanderers next Sunday.
"That's my aim - to try to improve and bring more goals and assists," he said. "But I'll be working on that in training with the manager and the players and hopefully I'll be able to help my team get more [goals].
"Everyone is disappointed but we're trying to not dwell on the mistakes that we made and the negativity. We just have to kick on."
