19. Alexandre Pato
When Alexandre Pato broke through at AC Milan, he was instantly compared to Brazilian legends like Ronaldo, Romario, and Kaka. He was the club’s top scorer in 2009 and looked to be on the fast track to superstardom. Unfortunately, Pato was unable to maintain that momentum. Injuries would stall his progress before he moved back to Brazil with Corinthians.
He had a second chance in Europe with Chelsea when he came in on a six-month loan. Apart from scoring a penalty on his debut, Pato did nothing. Now Pato is playing for his hometown club, Sao Paulo. He could have been so much more. It’s unfortunate because he faded away after an exceptional start to life as a professional soccer player.
