Goalkeeper: Hugo Lloris - 5/10
Could do nothing with Kabasele's goal.
Right-back: Kieran Trippier - 7/10
A constant attacking outlet. A lovely pre-assist for Son's goal and comfortably Tottenham's best player. The only Spurs man to constantly look a threat.
Centre-back: Davinson Sanchez - 3/10
Didn't look as comfortable in a defensive pair as he did in a trio. Shockingly stupid sending off for elbowing Richarlison really put his side up against it.
Centre-back: Jan Vertonghen - 4/10
A mostly solid performance. Failed to marshal his younger partner, however, and showed weakness when his side went down to 10.
Left-back: Ben Davies - 5/10
Attacked and defended well. Nothing special but definitely not a weak point.
Defensive midfield: Eric Dier - 5/10
Didn't really protect his defence as well as one would expect him to, winning just 1/4 tackles. Upped his performance when drafted into defence after Sanchez's red card, but then should have given away a last minute penalty with a handball. Got away with it, though.
Defensive midfield: Moussa Dembélé - 5/10
Nowhere near as dominant as one would expect. Failed to create a single chance.
Right-wing: Christian Eriksen - 5/10
Produced a wonderful cross for Son's goal. But didn't use the ball well enough (64% pass completion) and not strong enough defensively and was replaced as Tottenham went down to 10 men.
Attacking midfield: Dele Alli - 4/10
Carried the ball well but failed to truly create dangerous situations. Was the target of some physical play from Watford but did well to not rise to the bait. Was removed with five minutes remaining.
Left-wing: Heung-Min Son - 6/10
Tidy finish to draw Tottenham level. An energetic presence in the first half but got lost in the chaos of the second.
Striker: Harry Kane - 4/10
Took a knock in his attempts to score an early goal and didn't really find his feet until well after the hour when he turned into a terrific target-man for Tottenham. Never a goal threat and beaten in the air for Kabasele's goal though.
Sub: Moussa Sissoko - 6/10
Came on for Eriksen after 64 minutes. Added energy and drive to a Tottenham midfield playing mostly on the break. Was at the heart of their best chances in the final 30 minutes.
Sub: Erik Lamela - n/a
Came on for Son after 77 minutes.
Sub: Harry Winks - n/a
Came on for Dele Alli after 85 minutes.
