With Chelsea's loss and Everton's draw at home yesterday, it was important that Spurs capitalised on both teams' slip-ups, and thanks to an outstanding Gareth Bale goal, Andre Villas-Boas' men did exactly that at the Hawthorns.
The Welshman was Tottenham's biggest threat; his pace and directness caused the Baggies backline all sorts of problems and he always looked likeliest to score, which indeed he did in the 68th minute.
When Jermain Defoe departed the scene in the 35th minute, after picking up a serious ankle injury, there were no forward replacements for the 30-year-old which meant Spurs' goal-scoring burden laid solely with Bale.
It's worrying to think that, if Defoe is a long-term absentee (he was sitting on the bench with crutches), Tottenham only have Emmanuel Adebayor to rely upon up front. The Togolese is currently on African Cup of Nations duty and hasn't been in the best of form this season.
Not purchasing a striker in the January transfer window is something Villas-Boas and Spurs supremo Daniel Levy are going to regret. Defoe's substitute, however, Lewis Holtby, has been a shrewd acquisition. I wrote about the German after his cameo role at Norwich and once again he impressed, even earning himself a song from the Spurs support. He worked well in tandem with Bale and offered the intelligence Spurs have been lacking this season.
The 48th minute sending off of Goran Popov was the slice of luck that Spurs needed to nick a game that looked, in the first-half, to be heading for a stalemate. Mousa Dembele and Scott Parker began to dominate the midfield whilst the attacking players had more space to operate in. The dismissal also saw the dangerous and powerful Romelu Lukaku taken off.
I think Hugo Lloris deserves some praise too. His proactive style is really helping to cement the high pressing style Villas-Boas is looking to implement. The Frenchman's aerial commandant today relieved a lot of pressure at set-pieces whilst his smart save from a Shane Long shot in the 21st minute ensured the scores remained level.
Defoe's injury puts a dampener on today's win, but the performances of Bale and Holtby offer encouragement for a Spurs team that will now be looking for goals from midfield.
