Former City man Moses Odubajo had the first effort on target for the lacklustre hosts after 20 minutes, but keeper David Marshall parried his low driven effort wide.

Campbell then rose unmarked in the box to power home Grosicki's left-wing cross after 24 minutes to put Hull ahead.

The goal sparked the Bees into life and they hit back within five minutes when Mokotjo passed into the bottom corner from the edge of the box after a quick turn and pass from Benrahma.

Maupay then had a great chance but drilled his effort just wide of the far upright.

Benrahma had the ball on a string and put the hosts ahead just after the half hour with a dribble past three Tigers defenders that ended with a curled finish into the top corner.

Hull, who started the game so brightly and at a high tempo, were rocking and it was no surprise when the Londoners extended their lead, Maupay squaring from the byline for Benrahma to clip the ball past the keeper.

Like the first half, Hull started much the brighter after the break and only a save from largely untroubled Brentford keeper Daniel Bentley denied Goebel Evandro's long-range effort straight from the re-start.

Brentford then made it four, Ollie Watkins bursting clear down the right only to see his shot blocked by Marshall, before he headed back across goal where the waiting Maupay tapped home from close range.

It was all Brentford now and Maupay and Yoann Barbet both had chances to add to the scoreline, only point-blank saves from substitute keeper George Long keeping the rampant Bees at bay.

Benrahma claimed the match ball with another superb finish with nine minutes remaining when he curled the ball nonchalantly into the top corner from just inside the box.
