Bournemouth thought it had sealed another fine away win until Kepa Arrizabalaga brought down Son in the box, with the Spurs captain stepping up to score the spot-kick. 

Marcus Tavernier put Andoni Iraola's side ahead three minutes before half-time, with his finish made simple by Milos Kerkez's driving run and sensational pinpoint delivery.

The Cherries thought they had doubled their lead when Justin Kluivert rounded off a swift counter-attack, but it was ruled out for an offside against Antoine Semenyo in the build-up.

But the visitor would go further ahead just after the hour when Kluivert's neat turn saw him play in Evanilson, who dinked the ball over the on-rushing Guglielmo Vicario. 

Spurs, however, reduced the deficit just two minutes later when Pape Sarr's attempted cross looped over Kepa, with the visiting goalkeeper involved once again late on. 

Kepa rushed out to claim the ball but instead clipped Son in the area, with the Spurs captain dusting himself down before converting from 12 yards to seal a share of the spoils.

Bournemouth missed the chance to close the gap on the top four but climbed one place to eighth, above Newcastle United on goal difference. Spurs, meanwhile, stay 13th.
