Chelsea came from 2-0 down to beat Tottenham 4-3 on Sunday and go second in the Premier League thanks to two Cole Palmer penalties.
Dominic Solanke and Dejan Kulusevski gave under-fire Spurs boss Ange Postecoglou a dream start.
But his cavalier attacking approach will come under more scrutiny as Chelsea roared back to extend their unbeaten Premier League run to seven games.
Jadon Sancho gave the visitors a foothold before they dominated the second half with Palmer twice cool from the spot, either side of Enzo Fernandez’s strike.

Chelsea close to within four points of leaders Liverpool, who have a game in hand after their visit to Everton on Saturday was postponed due to high winds.
Son Heung-min’s 96th-minute goal was little consolation for Spurs who have won just once in seven games and remain 11th in the table.
Postecoglou was involved in an angry confrontation with his own supporters after a dismal display in a 1-0 defeat to Bournemouth on Thursday.
Spurs have often saved their best for the biggest games this season, beating Manchester City twice and cruising to a 3-0 win at Manchester United early in the campaign.
Postecoglou’s men flew out of the traps to leave an in-form Chelsea chasing shadows in the early stages.
