LONDON (AP) — Mauricio Pochettino listened to the boos ring out at Stamford Bridge after his Chelsea side slumped to another disappointing loss in the Premier League.

Across London, Ange Postecoglou was greeted by a standing ovation from his Tottenham supporters after another impressive performance by Spurs against archrival Arsenal.

The two managers’ contrasting starts to the season were underlined Sunday by Chelsea’s 1-0 home loss to Aston Villa while Tottenham drew 2-2 at Arsenal’s Emirates Stadium.

Pochettino, the former Tottenham manager who took over Chelsea in the offseason following a chaotic season that saw the Blues go through three coaches, now has just one win and three losses to show for his first six games in charge. The latest defeat came after Chelsea’s Malo Gusto was sent off in the 58th minute and Villa forward Ollie Watkins scored the winner in the 73rd.

Postecoglou, meanwhile, is still unbeaten in the league after passing his biggest test yet in his first north London derby.

Son Heung-min scored both goals for Tottenham, which came from behind twice after an own-goal by Cristian Romero and a penalty by Bukayo Saka. The second equalizer came just 23 seconds after Arsenal had regained the lead, following a huge mistake by Jorginho, who dawdled on the ball in midfield and gave the ball away.

On a busy Sunday schedule featuring five Premier League games, Liverpool climbed into second place with a 3-1 win over West Ham at Anfield, while Brighton beat Bournemouth 3-1 behind two goals from substitute Kaoru Mitoma.

Newcastle was hosting Sheffield United in the late game.

CHELSEA SHUT OUT AGAIN

Chelsea’s attacking woes were on display again despite dominating much of the game until Gusto’s sending off. The Blues have scored just five goals in six league games, with only one of those coming from starting striker Nicolas Jackson.

Jackson missed his best chance in the first half when he was teed up by a defense-splitting pass from Mykhailo Mudryk but saw his shot saved by Villa goalkeeper Emi Martinez.

Gusto was sent off for a challenge on Lucas Digne that was upgraded from a yellow card to a red after a VAR review, and Villa took advantage when the visitors won the ball back high in the Chelsea half to launch a counterattack.

Levi Colwill slid in to block Watkins’ initial shot, but the Villa striker reacted quickest to seize on the rebound and lash his second effort past Robert Sanchez from an angle and in off the far post.
