Neil Crowe felt that individual errors had proved costly for Bamber Bridge in their FA Cup defeat at the hands of rivals Chorley.
Brig were beaten 4-1 at the Sir Tom Finney Stadium in the third qualifying round tie.
The NPL First Division North team played some decent football but the mistakes they made were punished by a Magpies side who are two divisions higher up the pyramid.
“At the end of the day it is mistakes which have cost us the game,” Brig boss Crowe told the Evening Post.
“I thought we matched Chorley. But the higher you go these teams will punish you and Chorley did that.
“At 2-1 I thought we could get something from the game but then another individual mistake was made and it was 3-1 and then four.
“Maybe the two-division gap showed. But there are some good teams in our division who would have hurt us if we had made those mistakes.
“It is something that we need to cut out because it has happened in a few games this season.”
Brig fell behind in the 22nd minute to a James Dean goal.
The burly striker found the net after keeper Lee Dovey and Andrew Teague had collided in the box.
There was a suggestion that Dovey had been fouled but Crowe had no argument with Teague’s challenge.
Dovey needed lengthy treatment and managed to soldier on until half-time when he was replaced by goalkeeper coach Stuart Barton.
Said Crowe: “The lad has gone in with the keeper and won the ball so I’ve no complaints about that.
“He was left limping but it was what led up to that in our play which brought that challenge about.”
Crowe also saw midfielder Paul McKenna hobble off in the second half after a challenge from Dale Whitham, the loss of the ex-Preston player a big one.
“Paul got a kick, Chorley are a physical side and the higher you go, players are more cute,” said Crowe.
“The lad has stood on the back of his ankle, it hurt him and he couldn’t carry on.
“Paul has done well for us, he talks to the lads, gives them a lot of information, encouragement.”
McKenna revealed later that it been more of a twist rather than the challenge itself which had caused the problem.
“I got my leg stuck between his legs and twisted my ankle,” said McKenna who joined Brig last month after a season out of the game.
“I’ve had it strapped up and hopefully it won’t keep me out for longer than a week or two.
“It was a tough game and I thought we did okay at times but maybe a bit of inexperience told. There are some young lads in the team.
“I’m enjoying playing again and this was the fittest I had felt since I came back.
“So it was a bit frustrating to get the injury and having to come off.”
Brig will take consolation from a sell-out crowd of 2,214, the fifth highest in non-league football on Saturday.
Crowe said: “Financially the club has done very well.
“The bar must have been packed for three hours and the money from the gate receipts will go a long way to helping the club in the future.
“It was nice to get a run in the FA Cup – it was a good week looking forward to the game.
“You dream of trying to get to that first round but there is always next year. I’ll be keeping an eye on who Chorley get.”
