Spurs' Son Heung-Min has been one of the best players in the Premier League this season and he knows if his quality drops then he might have to answer to his dad again, and he wouldn't want another punishment from the man who coached him.
Just a few weeks ago Son Heung-Min was on such incredible form that the South Korean had put Spurs right in the middle of a genuine title race and he was being spoken about as a potential Player of the Year candidate.
It's no real surprise that since Son has last his scoring boots Mauricio Pochettino's side have seen their title aspirations.
The South Korean hasn't scored in the last four games and in that time the team have picked up just one point, the draw against Arsenal, losing to Burnley, Chelsea and Southampton.
Before that dip Son had scored four in four and 11 in 12 in all competitions, leading to the talk that he might be up for some major end of season awards.
It's no wonder that he wants to play well all the time. Speaking with the Guardian the former Bayer Leverkusen player revealed that when being coached by his dad he, and his brother, would be punished by having to do four hours of keepy ups, saying:
"He gave us four hours of keepy-uppies.
"Both of us. After about three hours, I was seeing three balls. The floor was red [through bloodshot eyes].
"I was so tired. And he was so angry. I think this was the best story and we still talk about it when we are all together. Four hours keeping the ball up and you don't drop it. That's difficult, no?"
Asked whether he let the ball touch the floor in that time the 26 year old said, 'No, not once,' that's some impressive control for a kid.
You'd be worried about making any mistakes and quite frankly no matter what Pochettino does to punish Son won't come close to that surely.
There was more though, Son's dad, who was a professional player in South Korea, came into his school to coach and made everyone do keepy-ups, with the Spurs player adding, "When I was 10 or 12, he came in to coach my school team and we were training, 15 or 20 players. The programme was for us all to keep the balls up for 40 minutes. When someone dropped the ball, my father would not say anything. But as soon as I dropped it, he made us all start over from the beginning. The players understood, because I was his son and, yeah, it was tough. But when you think about it now, this was the right way."
Cheers, Son's crying! Or at least he would be after all those keepy ups.
