Tottenham Hotspur's 1-1 draw with West Bromwich Albion was a stark reminder that it will take one hell of an effort to maintain a title challenge into 2018, with Manchester City threatening to run away with the Premier League and Spurs slipping to fifth after their recent disappointments.

That said, it was not all bad for Tottenham, with one player in particular proving just how important he has become for Mauricio Pochettino's side.

Heung-min Son should be reaching his peak in the next couple of years, and against West Brom he was superb, doing his best to change the game and ensure Tottenham picked up more than a solitary point.

The South Korea international has been in and out of Spurs' starting line-up this season, yet on the latest evidence he should be one of the first names on the team sheet.

He offers the flair, energy and additional creativity Tottenham need when some of their star names are under-performing, and he can make the difference in the toughest clashes.

His match-winning goal against Crystal Palace earlier this month spoke volumes and, while the international break no doubt played a factor, Son really should be starting games like the North London derby, not just coming on for the last 15 minutes.

On Saturday the Tottenham man proved his worth and he could step up to become one of their most important and consistent players in the months ahead.
