BARNSLEY put together a dominant display away at promotion favourites Brentford to secure three points on Valentine's Day.The Reds are now 12th in the league, one of five teams on 39 points, having inflicted the Bees' first loss in 22 league games.Reds head coach Valerien Ismael showed his intent at the Brentford Community Stadium with a physical front line featuring Carlton Morris and Daryl Dike, who was making his first start after his loan from Major League Soccer club Orlando City.The latter also made his first contribution for Barnsley early in the second half, setting up Morris who could net on 47 minutes after Ethan Pinnock failed to clear the American's low ball in from the right.That goal bolstered Conor Chaplin's 13th-minute strike, as the forward slotted home from Callum Brittain's left-footed cross from the right for his first goal in 13 Championship games.Brentford came into this game on red hot form, having not lost in the Championship since October 24 when they were beaten 3-2 at Stoke City - their third loss of the campaign.The Bees sat second in the league, a point behind Norwich City and four ahead of Swansea whose Saturday fixture at Sheffield Wednesday was one of several postponed due to the weather.But they have not beaten Barnsley at home in the Championship, with the Reds also buoyed by a strong performance against Chelsea in their mid-week FA Cup fixture - albeit with poor form away in the league which had only yielded four wins.Barnsley - who stunned visitors Chelsea at times, despite a narrow loss by a single second half goal - kept up their high-intensity pressing game against the Bees. They didn't allow the home side any time on the ball, regularly resorting to fouls to stop their momentum.Ismael substituted his front three, who had pressed the Bees backline relentlessly from the first kick, on 56 minutes.Cauley Woodrow and Victor Adeboyejo, on for Dike and Morris, combined to produce a wonderful effort a few minutes later when the latter hit a half-volley after Woodrow had chested it down on the edge of the box. But the ball sailed wide of the post.Brentford flattered to deceive at points last season, including in Barnsley's 'Great Escape' at Griffin Park as Clarke Oduor secured their survival with his 93rd-minute winner. That goal also consigned the Bees to the play-offs in their second-last appearance at their old ground.But the Bees' unbeaten league run, which includes a 1-0 success at Oakwell in November thanks to ex-Reds loanee Ivan Toney, suggested they'd shaken off any inconsistencies.Toney has been involved in 32 of Brentford's 55 goals, ranking him alongside some of Europe's most high-profile strikers for productivity.He came into the game leading the league's goals and assists tables, but was marshalled well by Mads Andersen, Michal Helik and Michael Sollbauer - the latter coming in for Toby Sibbick, who was a second half substitute.Toney had a penalty shout turned down on the hour mark as he tried to get to a Vitaly Janelt free kick but claimed to have been pushed in the back by Andersen. The forward also lifted an effort over the bar in the dying minutes from a Mathias Jensen free kick.Pinnock had two shots blocked by Dike on 39 minutes after a dead ball, and Saman Ghoddos had a good chance saved just before the half-time whistle after being played inside by Sergi Canos from the left following Toney's quick free kick.Collins denied another long-range effort on 67 minutes from Canos on Brentford's left, but the Reds continued to disrupt the home side's rhythm until the final whistle with a commanding, muscular performance.
