Tottenham kept up the pressure on leaders Chelsea with an impressive home victory over Watford, their sixth consecutive Premier League win.
Watford had started brightly, but Dele Alli's sumptuous strike - curled into the top corner after Son Heung-min's pass - signalled their quick decline.
In just 11 minutes they were three behind as Eric Dier smashed in from Son's deflected cross, before the South Korea forward added a third just before the break, firing in a rasping drive following Christian Eriksen's pass.
After half-time it was much the same story, with Watford only threatening in isolated moments, and Son further confirmed Spurs' dominance by meeting Kieran Trippier's perfect cross with a lovely half-volley at the far post.
