Tottenham finishes Watford in Premier league match (4 – 1)
Spurs dominated from the off at Vicarage Road – having 13 shots in the first half alone – and seconds after Alli struck the bar, Kane coolly finished a well-weighted Kieran Trippier pass.
The same duo combined for the second, Kane stealing between two static defenders to prod home Trippier’s fine cross from six yards.
It was the England striker’s 59th goal in his first 100 Premier League appearances, matching Arsenal legend Thierry Henry.
Alli made it 3-0 by passing low into the net after Younes Kaboul skewed the ball into his path, then arrived unmarked to finish Kane’s cross for his fifth goal in three matches.
Watford, who did not have a shot on target until Kaboul bundled home a late consolation, drop to 13th having won just once in seven matches.
Spurs’ fourth successive win takes them into third place, though Arsenal will pass them with victory over Crystal Palacelater.
