The South Korean returned to Tottenham training on Monday after his summer break.

Tottenham posted a video of Son as he arrived for training.

Son is one of the happiest people in football and almost always has a smile on his face. However, many football fans think he didn't look in the best of spirits as he made his way into training.

In fact, many are claiming that the club have actually 'broken' the 28-year-old.

To be honest, he could only be tired from the return trip or he might have lacked sleep. People got a tons of time to lose to try and see more there is about these kind of things. Hopefully at least its nothing worse, I would hate to think Son is actually truly broken or anything like that.

LOL Tottenham breaking players. Kane, Son, Lloris should all play for bigger clubs I think

Returning to Spurs from holiday would break lot of people

That, my friends, is called fatigue! I suspect lots of players returning to preseason camps to have this look after the last 15 months or so they have had. haha

He misses all the glamorous life and K-pop stars in Korea, and an top of that it was a long flight... that's all.

Pff a non-story, do you have other stuff like that to upload?
