Richarlison scored twice as Spurs ended their five-game winless run with a scintillating 4-1 thrashing of top-four rivals Newcastle at the Tottenham Hotspur Stadium.
Making his first start since October, Richarlison converted a Heung-Min Son cross from close range for his first goal then added his second from a looping Pedro Porro pass in the second half.
Earlier, defender Destiny Udogie had given Spurs the lead when he powered home another left-wing delivery from Son, who later added their fourth from the penalty spot having been brought down by Newcastle goalkeeper Martin Dubravka.
The win keeps Spurs within three points of the top four and puts them three clear of sixth-placed Manchester United. Newcastle, meanwhile, now sit seven points off fourth place in seventh.
