A goal from Arthur Read and a Jaden Brissett penalty proved the difference in very wet conditions north of the border.

It was the home side who saw more of the possession in the early stages with The Bees being forced to defend in the opening encounters with Simon Andersson forced into a relatively routine stop on 11 minutes from Armstrong Oko-Flex.

Despite that, it was Neil MacFarlane’s side who would go ahead first when David Titov did excellently to break down the right-hand side before pulling the ball back for Arthur Read to sweep a low effort home through a crowd of bodies on 15 minutes.

The game continued with Celtic looking to penetrate through the Brentford back line, which was being marshalled well by Luka Racic and Japhet Sery Larsen.

Andersson was once again called into action later in the half to deny Cameron Harper’s low effort at goal, but it would be Gustav Mogensen who would see the last action of the first period when he helped win the ball back high before shooting low and forcing the Celtic keeper into a smart save.

The second half was just a few minutes old when the home side drew level when Oko-Flex cut in from the left-hand side before firing well into the far corner to make it 1-1.

But The Bees didn’t let that goal affect them as they almost instantaneously gave themselves the opportunity to go back in front as the ball was crossed in from the left before a Celtic handball in the area, which left Brissett to slot home into the bottom left-hand corner.

On the hour mark the game further swung in Brentford’s favour when an off-the-ball incident featuring Mogensen saw Celtic's Jack Hendry dismissed with a straight red card.

Despite Brentford’s numerical advantage it was actually Celtic who were seeing more of the ball in the 10 minutes following the sending off, and they almost levelled when the dangerous Harper saw his left-footed effort come back off the post.

Credit to Neil MacFarlane’s side, though, who managed to wrestle back control and keep possession well, with the only negative in the later stages coming when Fredrik Hammar picked up a second yellow card for kicking the ball away meaning both sides finished with 10-men.

Despite that, the win means the young Bees will go into their two matches next week with confidence following what has been a positive run.
