Brentford Manager Mark Warburton said he had seen nothing like his team’s penalty shoot-out Capital One Cup win over Dagenham and Redbridge, and did not want to again.

The Bees progressed to the Second Round of the competition 4-2 on spot kick after a remarkable 6-6 draw in East London.

Brentford took an early 2-0 lead as Stuart Dallas converted a pair of crosses from debutant Montell Moore after short corners.

Nick Proschwitz scored his first Brentford goal to make it 3-1 just past the half hour but Dagenham levelled with strikes either side of half time.

Andre Gray put Brentford back in front and Moore restored the lead again after a late goal had forced extra time.

Dagenham then looked as if they had won it when they went 6-5 up after Tommy Smith had to limp off, reducing The Bees to ten.

But with Moore struggling with cramp, Harlee Dean headed an equaliser and Richard Lee saved two penalties as Brentford won the shoot-out.

Speaking after the game, which equalled the record for most goals in a League Cup tie, Mark said his team had to be better and let a position of dominance slip.

“The players used the words ‘embarrassing’, ‘frustrated’, ‘disappointed’ and they are right,” said the Brentford boss.

“From a position of total dominance in the first half, when we were playing some very nice stuff, moving the ball well and looking like, with no disrespect, we could have more goals suddenly conceding just before half time.

“There was some sloppy defending, poor decision making and I have never seen a game like it in my life.

“We will learn from it and there were lots of positives.

“Young Montell came in and was out on his legs.

“We had to take Tommy Smith off so we were effectively down to nine at the end.

“But, the fact is, we have to be better than that.

“I don’t want to see another game like that.”

Brentford included a number of experienced players despite making changes from the Sky Bet Championship draw against Charlton Athletic.

Mark said The Bees should have finished the home side off when they were on top.

“The team tonight included Richard Lee, who has played in The Championship, Nico Yennaris, who has been pushing Alan McCormack for the right back slot really hard, Harlee Dean, we all know his ability, Tony Craig and Kevin O’Connor,” he said.

“Kevin has been coaching and I asked him to step in and do a job for us tonight.

“Marcos Tébar and Toumani Diagouraga were also in the team.

“We had some good players out tonight and I thought the performance in the first half showed that.

“There was some god football, chance after chance and we have to finish off teams earlier in the proceedings.”

Mark said Brentford had to learn from their defensive lapses.

“We want to attack and be fluid and there were some very positive passages of play,” he said.

“We can’t be open and naïve at the back.

“Yu can’t leave yourself open to the counter.

“We were split, too far apart at times, too much distance between units and we went from in control to them being in it at 3-2 at half time.

“That shouldn’t be the case; we have to learn from it.

“There are fine margins.”

Mark said Nico Yennaris had to be taken off after taking a knee to the back and Tommy Smith had a groin problem.

“Nico has a similar injury to one Moses Odubajo picked up,” he said.

“He got a knee to the back and has the equivalent of a dead leg in his back.

“Montell had cramp and Tommy had a tight groin.

“He knows his body; we took him off as a precaution rather than lose him for four weeks.

“Scott Hogan is back in training, he will come back when he is ready.”

Mark answered further questions on Adam Forshaw.

The midfield player has been subject to bids from a rival club that have been rejected as they do not meet Brentford’s valuation of the player.

Mark said he spoke Adam, who had ankle surgery in April, on Monday but nothing had changed.

“I saw Adam Forshaw on Monday,” said Mark.

“He is OK; he is getting back to fitness after his operation.

“He reported a hamstring niggle and that is being treated.

“Nothing has changed with Adam Forshaw.

“You all know the interest, I understand that it unsettles.

“Any player is for sale if the price is right, we have a valuation and business can be done.”
