By the time the third goal went in, the Leicester fans had seen enough. Only half an hour was on the clock but off they trudged, up from their seats, and down into to the concourse. Anywhere but here. Anything but watching this.
Those sat closest to the Brentford supporters waved them goodbye as they went to the tune of ‘Cheerio, cheerio’ from the jubilant travellers.
Those that stayed turned their voices on everything in front of them.
‘You’re not fit to wear the shirt,’ they chanted to the players. ‘Sack the board,’ they called to those in the directors’ box.
Can you blame them? This is a club that not so long ago won the FA Cup, the Community Shield and challenged for European competition. It’s nearly 10 years ago now but, still, one that won the Premier League title.
Whatever people might say about delusions of grandeur in recent times, they certainly don’t deserve this. Even as a promoted side, they should be better than this.
But these fans have now watched their team lose 10 of their last 11 league games after Yoane Wissa, Bryan Mbeumo, Christian Norgaard and Fabio Carvalho completed the most routine of victories.
Leicester are now the first side in English top-flight history to lose six straight matches at home without scoring.
Supporters have become so disillusioned with the mismanagement of the club that a group of fans led a protest march to the King Power Stadium for their last game here to Arsenal.
It wasn’t needed this time, the patches of empty blue seats dotted around the ground before kick-off spoke loudly enough. They’d become swathes long before half-time.
Friday night under the lights? We’d rather stay at home and watch it on the box, thanks. At least you can just switch over to Gardener’s World.
Those who were here made their voices heard. Chants of ‘sack the board’ greeted Brentford’s third goal. Deafening boos met the half-time whistle.
Perhaps it could have been different had Leicester converted either of their early chances as Woyo Coulibaly and then Jamie Vardy, charging through on the counter-attack, both had shots saved by Mark Flekken in the opening minutes.
But then this is a side that last scored 76 days ago.
Few sights still stir the soul like Vardy bursting through on goal but even those flashes of the good times was never going to be enough to silence the frustrations as cries of ‘We want Rudkin out’, directed at the club’s director of football Jon Rudkin, erupted from the home end after 14 minutes – the number seconds Leicester were famously late in registering the signing of Adrien Silva eight years ago.
And certainly not when Brentford took the lead three minutes later as Boubakary Soumare gave the ball away, Mikkel Damsgaard split the Leicester defence with a single pass and Yoane Wissa did the rest.
Just 10 minutes later, it was 2-0. Damsgaard found Mbeumo on the right, who cut inside on to his left foot and curled a delightful effort into the far corner.
‘You’re not fit to wear the shirt,’ came the chants from the home fans.
When Christian Norgaard nodded in Mbeumo’s free-kick at the near post to make it three just after the half hour, those cries moved towards the club’s board.
Keane Lewis-Potter had the ball in the net on the stroke of half-time but a handball in the process saw it ruled out.
It was all so simple. And when it comes to this Leicester side under Ruud van Nistelrooy, all so predictable. No confidence, no organisation, no hope. Keep playing like this and Leicester will be celebrating their 10th anniversary of their title win back in the Championship.
In his 13 league games in charge, van Nistelrooy has scored fewer goals, conceded far more and won fewer points than predecessor Steve Cooper.
Mads Hermansen denied Brentford a fourth tipping away substitute Yehor Yrmoliuk’s glancing header before Wout Faes flung his way into the path of Wissa’s shot.
Not that it was enough to spare any blushes, their cheeks had long since flushed and the fury that met the final whistle from the few that still remained after Fabio Carvalho had made it four made sure of it.
