Another set-piece cost Carlisle United on Saturday.

The Blues fell behind to Forest Green when Jamille Matt converted a corner in the first half.

It was the latest dead-ball situation that has cost the Cumbrians in recent weeks.

They shipped an opening goal from a corner in the defeat to Crawley last month and then conceded two from corners in the draw with Scunthorpe.

It has been a persistent problem for the Cumbrians and it sent them on their way to a 2-0 defeat in their latest game.

Beech said Matt had managed to get away from league debutant Jonathan Dinzeyi in order to put Forest Green ahead.

Asked in general about United’s set-piece struggles, he said: “I think in the other fixtures that was more of a concentration [issue] and a lack of intense thoughts when the game’s dead.

“The ball goes out of play, it’s important to stay concentrated and energised.

“When you look at the goal at Crawley [and the two for Scunthorpe], you’ve got the situation where the lads have got their man markers and we’ve got two screeners, and when I look at the goals in detail, they’re all avoidable if the lads are doing what they normally do.

“This time they did that better but you are playing against a player [Matt] that sniffs a goal in those situations; he knows they’re his bread and butter to try and get his 15-20 goals, and he got he better of Jonathan on one occasion really, and it goes in the back of the net. It happens.”

Beech felt Arsenal loanee Dinzeyi had “responded well” on his first league start.

“He did have shaky moments within that solid performance, and it’s a case of tying up that,” the head coach said.

“You learn that in time. In terms of our shift, while he learns that, I want him to be learning in a winning team, not one that gets beat while he gets better.

“A lot of teams in the past have had that. Crewe would often not win many games over time, or when Dave Artell first got the job. They were allowed to lose, get stronger, grow and then become very good.

“Of course Jonathan’s not our player. While he’s in our remit, he adds to the defensive covers, and while he’s learning we still want to be winning.”

Beech admitted it was frustrating that United had not taken their chances early in Saturday’s game.

“It was very frustrating. But it happened. When you’re in these moments you have to accept them,” he said.

“What I was really pleased about, and I did say it to the lads after the game, what we’ve done is played very well and not won, got beat 2-0, it’s not really acceptable but on the back end of what happened last Saturday [the 4-0 defeat at Sutton] it hurts more.

“We have to take the responsibility of that fact on and make sure we iron it out over the coming games.”

Beech said he was happy with the way full league debutant Brad Young had competed in attack.

“That’s what we do, what I’ve done,” he said, referring to giving young players a chance.

“Often that’s dictated with outside factors but it gives young players opportunity.

“Brad did great. It’s a shame he couldn’t really get his chance and the chances he’d like to get shots off, but in terms of leading the line, holding the ball up, twisting and turning, bringing others into play and working hard he did that ever so well.”
