Michael Olakigbe's stoppage time winner saw Brentford B progress past Erith and Belvedere in the second round of the London Senior Cup 3-2. 

Lewis Chambers gave Erith the lead within ten minutes, before Lucias Vine struck back to get the young Bees on level terms before the break. 

Bradley Ryan then put Erith ahead once again within a minute of the restart, but Brentford came roaring back as Kyreece Lisbie equalised with two minutes remaining and then Olakigbe won it in stoppage time. 

This last gasp wins sees Brentford into the quarter finals of the London Senior Cup where they will take on the winners of Hendon FC against AFC Wimbledon. 

Erith got off to the perfect start as after four minutes the trialist goalkeeper for Brentford had to turn a low free-kick behind for a corner and the resulting set piece was whipped in and Chambers rose highest to nod it into the back of the net. 

The Bees looked to get back into the game as a quick exchange of passes saw Alex Gilbert released down the left side of the box and he looked to finish across Adam Molloy, but he got down to make the save. 

Then after 34 minutes Gilbert found space again between the lines and slid in Vine, who looked like he could have been offside but the linesman kept his flag down, he chopped back to get away from the covering defender and finished into the far corner. 

Brentford had another chance before the break as they played out from the back and found Gilbert, who had been at the heart of everything for the Bees, he split the defence with a through ball for Olakigbe, but his shot was blocked. 

Within a minute of the restart a long throw from Erith was hurled in and after a few deflections it fell to Ryan at the far post and he finished smartly into the near post to retake the lead for the hosts. 

Romeo Beckham made his debut off the bench and emulating his father he found space on the right and whipped a tantalising ball across the face of goal, but it was just beyond the reach of the outstretched Lisbie at the far post. 

Brentford could have been forgiven for feeling it wasn't their day as Lisbie got on the end of a cross from the left and hooked it up against the crossbar from two yards out and Beckham failed to scramble the ball beyond Molloy. 

With time running out, in the 88th minute a Beckham cross was half cleared and came to Lisbie, who did his best Anton Du Beke impression and danced beyond three defenders, before slotting beyond the 'keeper. 

Then two minutes into stoppage time Brentford completed the turnaround as a cross was headed to the top of the box to Olakigbe and his shot took a huge deflection and wrong-footed Molloy and rolled into the net.
