"We have responsibilities in terms of what we face on a football pitch but the one thing you need is heart and we didn't show any of that. I can only apologise to the fans behind the goal because they don't deserve this.

"Every time we take a step forward we take two steps back. I have said the boys train well and hard and a lot of it you don't see coming, and then you get that on the pitch.

"There is a leadership problem and I share responsibility for that. I have to lead that team and those players on a daily basis, but I'm clearly not getting a response.

"I understand that but I can only do what I can physically do. I have done all I can and it's not had the response that's needed. We were nowhere near it today.

"There's a culture here that will never ever be successful. We don't have enough desire, determination and character and if you want to be successful there has to be desire beneath you. There is not enough of that at this football club.

"It's not an individual thing. It's the whole team and there are deep rooted issues here for everyone to see. I am tired of saying it."

Asked about changing systems to combat a rampant Brentford side, Monk added: "The system wouldn't have mattered because if you don't play with heart you will be punished.

"We did well until Christmas but we've had a huge drop off since then and trying to find a way through it to rediscover that consistency is proving a very difficult thing to do.

"But I'm not a quitter and I've had to fight for everything in my career and I will also fight to turn this round until someone tells me otherwise."

Brentford head coach Thomas Frank said he hoped the demolition job would be the turning point in their promotion push.

The Bees had gone five games without a win, but the Dane was full of praise for his side's defensive mindset and desperate desire to preserve their clean sheet.

"We have drawn a few too many recently and some of that may have been down to the fine margins, but I hope this will mean we have turned the corner," he said.

"Our success is built on four main pillars of top attitude, hard work, performance and attitude and we showed all four from start to finish.

"Last season we knew the biggest thing to work on was our desire to defend. We had a February where we conceded some strange goals but today there were some fantastic blocks to protect our goal.

"That was as pleasing as seeing three or four of our players getting forward with real desire when we were four and five goals ahead near the end."
