Tottenham increased the pressure on Manchester United manager Jose Mourinho with a convincing 3-0 win in the Premier League at Old Trafford.
Harry Kane's precise header put Spurs in command at the start of the second half.
Lucas Moura's angled drive doubled their lead two minutes later as United's defensive frailties were exposed again.
The Brazilian rounded off the scoring late on, skipping past Chris Smalling to plant his shot beyond goalkeeper David de Gea.
Only a fourth league win at Old Trafford in 40 years maintained Tottenham's 100% record this season and lifted them to second in the table behind Liverpool.
United have lost two consecutive Premier League games and two of their opening three fixtures for the first time since 1992-93.
