Brentford recorded their second 1-0 home win in four days - this time over high-flying Colchester United.
A Charlie MacDonald goal inside the first 15 minutes was enough to give The Bees the points against a direct but talented and well-drilled Colchester side.
On a chilly night and with football difficult to play on a bobbly pitch The Bees made a mockery of the distance between the teams in the League One standings.
Brentford started brightly, and had the ball deep in Colchester territory, but the visitors probably had the better chances in a thrilling first 25 minutes.
Clive Platt forced an early save from the busy Wojciech Szczesny and Leon Legge made a vital block from John-Joe O'Toole when the Polish stopper failed to deal with one of numerous up and unders.
Anthony Wordsworth also had an effort blocked and a Kevin Lisbie shot dribbled through to Szczesny but Brentford were creating chances of their own.
When a John Bostock shot fell to MacDonald the striker almost opened the scoring when he turned nicely and fired a shot across Ben Williams, but it went just the wrong side of the far post.
But when MacDonald got another chance on the quarter hour he made no mistake.
A Ryan Dickson cross fell to Bostock on the right side of the area and although his first shot was blocked he found room to swing over a cross for MacDonald to head in from close range.
Colchester came roaring back and, although finesse was not high on the agenda on a badly cut up pitch, they showed why they are challenging for promotion.
Wordsworth fired a shot over before Kayode Odejayi created a shooting opportunity for Lisbie, he bundled past Dickson but as he prepared to level it up Szczesny rushed out to save superbly at his feet.
Odejayi almost equalised soon after when he got past Legge on the left side, his first effort was blocked and his second was saved by Szczesny with his legs after a deflection.
Brentford gradually regained a measure of control and Colchester's grip on the game began to weaken, by the end of the first half the home side were almost completely in control with The U's resorting to long ball forward after long ball forward.
Ben Strevens headed wide and the fired wide from 20 yards after bringing down a Pim Balkestein pass.
He went even closer soon after when MacDonald headed a Dickson cross into his path but his effort was half blocked and Williams saved high to his left.
Platt narrowly failed to reach a low Lisbie cross at the other and David Fox shot wide before Marcus Bean blasted high and wide from the edge of the box just before the break.
The second half did not live up to the end-to-end excitement of the first but with Colchester pushing forward Brentford were forced to defend well.
Long range efforts from Wordsworth and O'Toole flew wide early on and Sam Wood had a shot blocked at the other end.
O'Toole had a shot saved at the near post but the closest Colchester came to an equaliser was presented to them by Szczesny.
The Polish stopper kicked the ball clear from the left side of his area when he felt Legge's clearance would be adjudged a back pass and it dropped to Fox 35 yards out - the midfield man fired it back first time and it bounced just wide of the post with Szczesny scrambling across.
MacDonald headed a Dickson cross wide and Legge nodded a Bostock corner wide around the hour mark and with time ticking on Colchester started to throw bodies forward.
O'Toole was unable to connect with a shot from ten yards and Phil Ifil headed a Tierney cross wide.
But as the minutes ticked by Colchester's huffing and puffing was coming to nothing and The Bees rearguard - with Legge and Balkestein repelling everything thrown at them - stood firm.
Szczesny had to make a late save from a low Steven Gillespie shot which bounced awkwardly in front of him but he was equal to it.
Legge headed another Bostock corner wide as Brentford searched for the killer second goal but it proved not to be necessary as they took the points with the only goal of the evening.
