Tottenham scored twice in two first-half minutes to set up a victory over Crystal Palace and keep up the pressure on the Premier League top four.
Harry Kane opened the scoring with his second goal in as many games, before Lucas Moura doubled their lead with a powerful header from close range.
Palace, who had asked the Premier League to postpone the game because of a Covid-19 outbreak, which included a positive test for manager Patrick Vieira, never got going in north London.
With Vieira self-isolating, assistant manager Osian Roberts took charge of the team, which had to play for nearly an hour with 10 men.
Their talisman Wilfried Zaha felt aggrieved about his sending off for two bookable offences in the first half, before Son Heung-min sealed the win with a third for Tottenham after the break.
Spurs are unbeaten in six league games under Antonio Conte and are six points behind fourth-place Arsenal with three games in hand, while Palace are 12th in the table.
