Kane strikes landmark goal to sink West Brom
Harry Kane's 150th Premier League goal was enough to send Tottenham top of the table for the first time since August 2014.
A game of few chances seemed destined to end goalless after Hugo Lloris had kept out Karlan Grant's second-half header and a flurry of Tottenham chances had come and gone without reward.
But, as has been the case so often in the past, Kane punished a minor lack of concentration to head home an 88th-minute winner.
West Brom's defence failed to track the England skipper's run into the box, allowing him toleapuncheckedtomeetMatt Doherty's cross and guide the ball over goalkeeper Sam Johnstone. Tottenham's lead at the summit may have only last a matter of hours but it was the kind of narrow win that is the hallmark of champions.
Apart from the start of his final season at Manchester United, when they played a day before everyone else, this was the first time Jose Mourinho has been top of the table since September 2017. He has infused grit and organisation into an already top side - not to mention added Gareth Bale.
The Welshman was not at his best on this occasion, but he formed a potentially lethal attacking trio alongside Kane and Son Heung-min that will not be easily subdued.
Son could have made life a lot easier for Tottenham if he had taken an early chance that came hisway, but the South Korean saw Kyle Bartley block his shot. And when Doherty had an effort saved near the end, it seemed Spurs would have to settle for a point. But Kane had other ideas to send Spurs into the international break in a very healthy position, with Man City and Chelsea their next two opponents.
