Mauricio Pochettino must start Tottenham new boy Heung-Min Son against Sunderland

The 23-year-old could be the spark that gets the Tottenham Hotspur attack firing again.

Spurs head coach Mauricio Pochettino has a tendency to take his time bedding in new arrivals. The clearest example was that of Hugo Lloris, who was forced to play second fiddle to Brad Friedel for several games after his big-money move, before finally claiming the first-team shirt that was duly his.

Toby Alderweireld is the only summer signing to feature so far for the Lilywhites, with Heung-Min Son and Clinton N’Jie unavailable for the past two fixtures for varying reasons.

There are still doubts surrounding the former Lyon winger’s fitness, as he tries to recover after picking up a pre-season knock with the French club, so his involvement against Sunderland – from the start at least – seems unlikely.

Heung-Min Son, on the other hand, is most certainly fit and firing and bagged himself a hat-trick while on international duty with South Korea last week.

Tottenham today confirmed - via their official website - that the former Bayer Leverkusen man has been granted his work permit and given international clearance, leaving Pochettino with no excuse not to start him in Saturday’s game.

The right flank has been a weakness for Spurs for the past couple of seasons, with the likes of Erik Lamela, Andros Townsend and Aaron Lennon failing to make it their own.

Son is ostensibly right-footed but one of the strongest aspects of his game is his ability with his left, so much so in fact that it’s hard to determine which side he favours when watching him in action.

He played the majority of his football on the left flank or as a second striker in Germany last season but is more than comfortable on the right, and would provide the pace and goal threat that has been so sorely lacking on the right side.

A front four of Nacer Chadli, Christian Eriksen and Son behind Harry Kane is full of goals and creativity and should Pochettino take the plunge and throw the South Korean into the deep end, keeping Spurs at bay becomes a much harder task for Dick Advocaat’s men.
