Park Ji-Sung’s relentlessly energetic displays for Manchester United were the stuff of legend. 

But no legend or fairytale is complete without the addition of a frog and the South Korean has bizarrely revealed his secret weapon was ‘frog juice’. 

As a youngster with ambitions of making it to the top, Ji-Sung’s father would travel from Suquon to Go-heung to gather the wild amphibians for his son.

He then boiled the juices and make him drink it, under the guise that it would improve his strength.

Ji-Sung said: My father went to catch wild frogs.I was skinny and weak and my father heard their juice would give me size and strength.

‘It tasted very, very bad but I had to drink it because I wanted to be a footballer and everyone said I needed to be bigger and stronger.

‘They said it was good for my health to become stronger and I ate everything that would improve my health.’  

The dubious home remedy seemed to do the trick, with Ji-Sung becoming famous for his fitness and tenacity over 90 minutes. 

He went on to become the first Asian winner of the Champions League and also won three Premier League titles under Sir Alex Ferguson.  

The 37-year-old retired in 2014 and now acts as a United ambassador.
