A smooth Southampton sidelined Brentford to doom the Bees to their heaviest loss of the season.
In a night to forget for Thomas Frank’s side, the Saints took full advantage of a dismal defense and poor goalkeeper from Alvaro Fernandez to head for an emphatic victory.
The first sign of things to come, Southampton took the lead after just five minutes when Nathan Tella’s pace pushed him past Pontus Jansson, but his shot on goal went for a corner.
James Ward-Prowse’s perfect in-swinger then escaped Brentford’s defense but found unmarked Jan Bednerak who peeked past Fernandez.
However, that early setback woke the Bees up and they equalized brilliantly thanks to Vitaly Janelt’s softly-hit volley on a Bryan Mbeumo cross midway through the first half with their first real attack.
But that joy was shortlived as Southampton regained the advantage just before half-time when Ibrahima Diallo’s first effort bounced past Fernandez and off the post before making its way into the net. Spaniard after the Bees were only able to half-clear a corner from Ward-Prowse.
The Saints effectively sealed the win less than a minute into the second half when Oriel Romeu split Brentford’s defense with a perfect pass and impressive Chelsea Loanee Armando Broja passed Kristoffer Ajer and landed a shot Fernandez should have prevented.
As Brentford continued to struggle with the pace and movement of an impressive Saints side, the hosts added some shine to the scoreline with a fourth goal with 15 minutes remaining.
Once again, it was a defensive calamity on the visitors’ part as Jansson allowed a ball to bounce past him inside the box and Scotland striker Che Adams pinched past the Swede and touched Fernandez.
