Brentford manager Mark Warburton called on his players to be more clinical after they were held to a goalless draw by a dogged Carlisle United side at Brunton Park.

Warburton's side has taken just one point from the last two games after a 19-game unbeaten run came to an end the previous week against Wolves.

Warburton said: "We are disappointed with the way we dominated possession, but lacked a little bit of quality and we were sloppy at times.

"I never criticise the work-rate and approach to the game, but we have to get to the next level and be more clinical and hit the target.

"We have got to be clever and it's disappointing that our final pass, delivery and getting caught offside was sloppy and not typical of Brentford this season.

"We dominated the final stages and Carlisle will be pleased with the result as they were trying to kill the game at the end.

"There's great quality in the dressing room and if we can keep learning we will be ok. We have got to be more clinical and clever around the final third."

Warburton had particular praise for James Tarkowski, who made an impressive debut in defence for the Bees.

"We tracked him from when we played Oldham early in the season," Warburton added.

"He is very confident in possession and has a good range of passing, so his display has come as no surprise to us."

Carlisle manager Graham Kavanagh, faced with a big injury list, admitted that he had asked his young players to "go out and be men."

He said: "There was concern before the game and it was less than two hours before kick-off when I knew the shape of the team.

"There were some of the youngest players this club has put out and we told them to go out and be men and they were brilliant.

"All across the pitch the level of play was top class. The players answered some huge questions.

"It was a hard-earned result and it could have been three points. It was a tough afternoon."

Kavanagh hailed the performance of veteran defender Pascal Chimbonda, who had to fill in at centre-half in the absence through injury of Sean O'Hanlon and Matty Robson.

"Pascal was outstanding," Kavanagh added. "I've given him a bit of stick in the past and he took what we said on the chin. It was a magnificent performance."

Bees played a neat passing game, which gave them plenty of possession, but it was Carlisle who finally managed to test David Button in a lively spell after the break when the keeper had to keep out efforts from David Amoo, Liam Noble and Brad Potts in quick succession.

Brentford pushed forward in a bid to break the deadlock and Marcello Trotta just failed to turn a cross in from close range before Alan Judge hit a stinger of a shot from 25 yards, which Carlisle goalkeeper Jordan Pickford parried at full stretch.

Potts almost snatched victory for Carlisle with a fierce right-footed drive which flew narrowly wide.
