Sky Blues grab early opener through Callum Wilson which is overturned by strikes from Brentford's Donaldson and Trotta at Griffin Park at half time
Coventry City go into the break trailing 2-1 to Brentford at Griffin Park after Callum Wilson's early opener was overturned by strikes from Clayton Donaldson and Marcello Trotta.
Wilson put the Sky Blues ahead after just five minutes and Alan Judge had a penalty saved by Joe Murphy six minutes later.
Two goals in fou minutes from the Bees though turned the game on its head although the tie look far from over.
Boss Steven Pressley rang two enforced changes to the side that drew 2-2 with Port Vale at Sixfields the previous weekend, bringing in Nathan Delfouneso and Franck Moussa to replace departed loanee Michael Petrasso and fellow loanee Chuba Akpom whi had only recently returned from European reserve duty with parent club Arsenal.
The Sky Blues got themselves off to a dream start after just five minutes when they found themselves infront against the in-form Bees. A swift switch of play from left to right ended with Carl Baker drawing across the box before firing at goal, Brentford 'keeper David Button parrying the effort but Wilson on hand to turn the loose ball home from close range.
The early goal understandably gave City a boost as they turned up the pressure and very nearly grabbed a second after nine minutes after Franck Moussa's burst into the box won a corner which was taken short to Cyrus Chrtistie, the full back trying to curl one inside the far post only to see Button turn the ball behind.
Brentford were then handed a golden opportunity to level the score after 11 minutes when Carl Baker was penalised for a foul on Alan Judge just inside the area with referee Gavin Ward pointing to the spot.
Joe Murphy was the hero from the spot for City yet again though when Judge stepped up to take the penalty and Murphy guessed the right way to deny him in front of nearly 1,400 travelling Sky Blues supporters.
The home side only had to wait another four minutes for their equaliser though and it was taken in clinical fashion by Donaldson who was set free by a through ball on the counter attack which allowed him to hold off Jordan Willis as he entered the box before poking a finish past the advancing Murphy.
Brentford then turned the game on its head after 19 minutes when Marcello Trotta fired them in front. He picked up a ball 20 yards out and worked his way across the edge of the area before firing low past Murphy inside his near post.
Despite the Sky Blues finding themselves behind so quickly though they never changed their game plan and continued to press and Wilson very nearly got his second after 33 minutes when Nathan Delfouneso held the ball up before playing a quick pass to his strike partner who tried to lift a finish over Button but also lifted it just over the bar.
