Harry Kane struck a double as Tottenham reignited the battle to finish in the top four with a convincing 3-0 victory at home to 10-man Arsenal.
The England striker coolly converted a spot kick awarded for Cedric Soares’ foul on Son Heung-Min to put the hosts in front on 22 minutes.
The Gunners’ evening then took a further turn for the worse when Rob Holding was given his marching orders for a second yellow card following another foul on Son just past the half hour.
Kane took full advantage of Arsenal’s disarray when he boosted his tally in North London derbies to 13 goals overall, tucking in a flick-on from a right-wing corner on 37 minutes.
Spurs were in complete control and they made sure it would be a long second period for their rivals when Son netted within a minute of the restart to claim his 21st league goal of the campaign.
The result means fifth-placed Spurs move to within a point of Arsenal in fourth spot, with just two matches to play.
Next up, Spurs host Burnley on Sunday while Arsenal visit Newcastle on Monday.
Advantage Spurs? If there was a worst-case scenario for Mikel Arteta this was it. A resounding defeat with defensive deficiencies exposed and issues over personnel to consider with Holding set for a suspension and Gabriel appearing to limp off injured.
Fourth place remains in the Gunners’ hands, but it’s likely to now go to the wire. Spurs meet Burnley next and could be ahead of Arsenal prior to their clash at Newcastle. Arteta’s side then finish with battling Everton at home while Spurs are at rock-bottom Norwich.
The fixtures, the momentum and the goal difference appear to favour Spurs, but Arteta’s young guns have bounced back plenty of times already this season and will need to show real character from here if they to achieve their target.
MAN OF THE MATCH
Son Heung-Min (Tottenham). Kane will get the headlines for his brace but Son was the player Arsenal simply could not handle. Holding’s red card is testament to that as he capped another live-wire showing with a goal that moves him to within one of Mo Salah in the race to be the Premier League’s top marksman.
