Match report: Villa U18s 1-3 Bristol City U18s
Ben Petty admits a combination of individual mistakes and a lack of cutting edge in front of goal were costly as Villa slipped to a defeat against Bristol City.
The claret and blues squandered a host of chances in the first period but went in at the break with the score at 1-1 thanks to Connor Taylor's strike.
The Coventry-born forward met Jack Grealish's cross to convert a well-taken header from six yards.
But the Bristol outfit capitalised on some defensive errors after the break to emerge with three points.
It was Villa's third straight defeat in the Barclays Premier Academy League.
Petty said: "In the first half we thought we did ok. The lads played some good football and we should have been four or five up.
"We didn't take our chances but it was 1-1 at half-time and we thought in the second half the game was there for the taking.
"But again there were a couple of individual errors that have really cost us and I think that is the way it has been at the moment in the youth team.
"They are really learning harsh lessons with mistakes that are costing us goals."
But youth coach Petty praised the work of Taylor, revealing the striker has been encouraged to show his predatory streak in recent weeks.
He added: "It was an excellent goal. We've been trying to encourage Connor to get himself around that six-yard box more and poaching goals.
"He got himself in front of the defender and nodded it in from around six yards.
"That is Connor's strength and sometimes he does so much work outside the box for the team that lacks in his game."
