Mbeumo’s brace and a Yoane Wissa goal proved to be the difference between the two sides and condemned the Saints to a third straight loss since promotion back to the Premier League.

With departed striker Toney watching in the stands after his move to Al-Ahli in Saudi Arabia was confirmed before the transfer window closed, the hosts proved too strong for Russell Martin’s men.

They created the superior chances and capitalised on an error-strewn performance from Southampton’s backline.

Mbeumo opened the scoring on the stroke of half-time before doubling the lead halfway through the second period and Wissa then got on the scoresheet moments later to continue Brentford’s strong start to the campaign. Yukinari Sugawara bagged a consolation in injury time for the Saints.

Brentford sits in fifth place ahead of the first international break, while Southampton is second-bottom of the league table with zero points.

Brentford has recorded consecutive home league wins for the first time since last November, and the first time in its opening home games since August 2018.
