There aren't words to describe the skills that Cristiano Ronaldo has. If you're not convinced that he's the best player on Earth, this is for you. Cristiano Ronaldo has undergone so much training, that he's almost perfect on the pitch. In this video, he undergoes a series of tests to see how he is able to perform extremely hard tasks. The tests are done in a scientific lab. I can't really explain this video, but you definitely should take time to watch it.
