Spurs arrived at the Amex Stadium seeking a fourth successive top-flight success to reclaim fourth spot from reigning champions Manchester City.

But the north London club were ripped apart as Pedro's double and Estupinan's thunderbolt added to Jack Hinshelwood's opener.

Tottenham, who claimed late consolations through substitute Alejo Veliz and Ben Davies, could easily have lost by more as rampant Albion twice hit the woodwork and had a Facundo Buonanotte effort disallowed.

Richarlison struck a post for the visitors and was twice denied by the offside flag, while Pierre-Emile Hojbjerg also hit the woodwork.

Yet, on this evidence, Champions League qualification looks a distant dream for Ange Postecoglou's side, who had registered just one point from 15 before their recent upturn in form. Victory lifts Roberto De Zerbi's hosts above Newcastle into eighth.

Depleted were missing eight first-team players while their visitors also had a lengthy list of absentees.

One-time Arsenal forward Danny Welbeck should have opened the scoring for Albion inside six minutes when he was twice denied by goalkeeper Guglielmo Vicario, but the Seagulls deservedly edged ahead with 11 minutes on the clock.
