Two goals in 79 first-half seconds set Brentford on their way to a comfortable victory over Southampton.
Both sides began the day on 40 points but Brentford's victory moved the Bees up to 12th in the Premier League, 11 points clear of the bottom three.
They went in front when centre-back Pontus Jansson forced home Ivan Toney's cross from close range, before Yoane Wissa curled into the bottom corner from the edge of the penalty area moments later.
Kristoffer Ajer sealed the win in the second half when he skipped away from two Saints players in the area before poking the ball beyond Fraser Forster.
