David Unsworth says he was disappointed with his side's lack of ruthlessness in the final third after Everton Under-21s bowed out of the Premier League Cup with a 2-0 defeat at Huddersfield.
The young Blues, who were looking to record back-to-back wins after a 3-2 win over Sunderland earlier this month, came unstuck as second-half strikes from Will Boyle and Duane Holmes ensured the Terriers' place in the last 16 of the competition.
And Unsworth says it was uncharacteristic defensive errors that cost his side at the John Smith's Stadium.
"It was a very disappointing result," he told evertonfc.com. "The manner in which we conceded the two goals was very unlike us and, for all our control and possession, we didn't really threaten their goal enough for my liking.
"It leaves a sour taste really because we weren't at our best today - we have to be honest and say that.
"Our players were told what type of game it was going to be beforehand but, unfortunately, we didn't manage to create enough chances to warrant the win."
After a positive first half in which Conor McAleny and Chris Long went close with half chances, the visitors conceded a minute after the interval as Boyle's inswinging free-kick evaded everybody to find the bottom corner.
"It's always disappointing to concede from a set piece," added Unsworth. "We didn't take responsibility to deal with it and it's crept in at the far post.
"From there, we tried to change our shape a bit and make a couple of substitutions but it just wasn't to be our day."
