Matej Vydra, Chris Brunt and Stephane Sessegnon opened the gap in the first half at The Hawthorns, but a Jonas Olsson own goal provided Spurs a life-line, and Harry Kane and Christian Eriksen finished the job in the second period.
Following are ratings and analysis for all the Tottenham players.
Half-Time analysis for Tottenham Hotspur
Lloris: Punched the ball straight at Vydra for the opener.
Naughton: Delivered the cross that Olsson accidentally turned into his own goal.
Chiriches: A walking disaster.
Kaboul: His mistake led to Sessegnon’s goal.
Rose: Went down far too easily to win the penalty.
Lennon: Conceded possession in the attacking third just moments before Sessegnon broke downfield and scored.
Paulinho: Has completed 94% of his passes so far.
Chadli: Distribution has been good, although neither Kane nor Adebayor have been well-serviced so far.
Eriksen: Has had a few bright moments, but his teammates’ woeful defending seems to have taken the wind out of his sails.
Adebayor: His abysmal penalty was stopped easily by Foster.
Kane: Flashed a shot just wide of goal shortly after Spurs went 2-0 down.

Eriksen: Took his goal extremely well, switching the ball to his right foot before drilling it into the top corner.
Adebayor: Will be ruing that penalty miss, but he held the ball up nicely throughout the match.
