Billy Barr says fine margins cost his side after Rovers Under-23s suffered a narrow defeat to Everton Under-23s at Goodison Park on Monday night.
Ellis Simms' smart finish proved the diffference on Merseyside, but Rovers had their chances to draw the game late on into the contest, most notably through Jack Vale and Harry Chapman.
And speaking after the game, Barr was left rueing his team's ruthlessness in and around the home box.
“I thought we started okay and then Everton finished the half better than us," he admitted.
“I was disappointed with their goal, unmarked in the box from a free kick.
“Second half I thought they listened to what we asked of them, being braver on the ball, which was part of the game-plan but we forgot it for large chunks of the first half, and I felt we were the better team in the second half.
“If any team was going to win it then I thought it was going to be us, without being clinical around the box.
“We got in to some really positions," he added.
“Then we got caught out by something we knew was coming, the ball gets played in behind and the lad that finishes it, he scored 40 the other season for the Under-18s, so he knows how to score goals. He only needs that sniff.
“We huffed and we puffed late on. Joe Rankin-Costello put a great ball in late and I thought ‘where are we?’. That’s the difference, they’d have been on the end of that, we’re not.
“We have to get in positions where you can score goals more consistently and reap the rewards from that.”
