It is a problem in football, all these names. It's like they can just call themselves what they want.
Like when it turned out Ronaldinho meant "little Ronaldo" yet at the time he was bigger than Ronaldo, so Ronaldo was little Ronaldinho, which made Ronaldinho little little little Ronaldo.
Also Collins John. Was he born back to front? Did his birth certificate get printed the wrong way round amd his parents were too ashamed of him to get it changed? What would be the plural if there was more than one Collins? Or what if Collins was with two Colins and you needed to call Collins over but not either of the Colins? Then what?
