Burnley withstood a second-half onslaught from luckless Brentford before snatching two late goals to secure their place in the fifth round of the FA Cup at Griffin Park.

The First Division side led when Robbie Blake pounced on sloppy defending in the 52nd minute.

But Wally Downes' team refused to lie down and laid siege to the Burnley goal in search of an equaliser.

KEY MOMENTS

31 mins : Beresford tips over Leo Roget's header 51: Blake fires Burnley ahead 85: Paul Cook's curling effort makes it two 90: Substitute Glen Little seals victory

But Paul Cook and Glen Little broke their hearts with two goals in the last five minutes.

The First Division side took the lead when Blake tucked away his 11th goal of the season following wing-back Andy Frampton's indecision.

Brentford then launched a series of attacks, forcing goalkeeper Marlon Beresford into a series of magnificent saves as they threatened to equalise.

But a mistake by Ibrahim Sonko let in Cook for the second after 86 minutes, and Little wrapped it up from close range three minutes later.

Despite the scoreline, it was Brentford who had looked the most likely winners.

The difference was our finishing which was clinical Burnley boss Stan Ternent

They produced the best chance of a scrappy first half when Leo Roget's header was superbly tipped over by Beresford.

And immediately after Blake's goal they forced Beresford into another superb save to tip Jay Smith's header round the post.

People will look at that scoreline and think we got stuffed but anyone that was here will know the truth Brentford boss Wally Downes

Brentford continued to rain shots on the Clarets' goal as the game progressed.

But a combination of the cross bar and Beresford's athleticism frustrated Brentford and Burnley booked their fifth-round spot.
