#2: Ronaldinho
Ask any football fan about where Leo Messi learned his trade, and Ronaldinho would be the obvious answer. He is a vast institution when it comes to learning various aspects of the game.
Ronaldinho is regarded as the person who upheld the Blaugrana in their dark times. He is the undisputed reason why Barcelona stand today as one of the greatest football clubs around the globe.
As much as it was sad to see him depart, the Barcelona fans showed equal enthusiasm on his return with AC Milan in 2010. Not only the Barca supporters, it was as if the whole football world celebrated the king's return to his empire. Ronaldinho still wears the blue and burgundy shirt in charity fixtures for Barcelona. A wide uproar and applause were enough to tell about the respect Ronaldinho commands at the Nou Camp.
They say nothing is impossible. But ask any person to hate Ronaldinho and you will know how wrong the dictum is!
