TOTTENHAM DOMINATED POSSESSION at The Hawthorns only for former Spurs star Nacer Chadli to put the Baggies ahead eight minutes from time.
But Dele Alli’s 89th-minute equaliser preserved Spurs’ unbeaten league record.
Tottenham manager Mauricio Pochettino said: “We missed the opportunity to achieve three points but in the same way it was a difficult game.”
Liverpool will go level with the top two, Arsenal and City, if they beat bitter rivals Manchester United on Monday.
Stoke won in the league for the first time this season as Wales international Joe Allen made it four goals in his last three games by scoring twice in a 2-0 win at home to basement club Sunderland.
Elsewhere, Bournemouth thrashed Hull 6-1 as Mike Phelan’s first game in full-time charge of the Tigers ended in an a thumping defeat.
Charlie Daniels put Bournemouth 1-0 up as early as the fifth minute. Hull’s Ryan Moses equalised in the 34th minute but from then on it was one-way traffic as Steve Cook and Junior Stanislas (two goals), Callum Wilson and Dan Gosling all finding the back of the net.
Phelan, who took caretaker charge of Hull after former manager Steve Bruce left in pre-season, was scathing about his side’s display.
“I feel very embarrassed,” he said. “We’ve got to grow up…What we’ve done today is not good enough.”
