What the EUROPEANS teams (not just Liverpool) would be without players of South America, Africa...and other contries?
Can u understand now?
They'd do ok. Many South Americans come to Spain, but also people from Serbia, Romania, Bulgaria, Russia, from Cameroon, etc.
In my country there's a team, Bilbao, composed by only basques (that's why I hate them, they want our youngster diamonds since our factory is better than theirs) and have never been in second division and won titles, it'd be like a Tottenham Hotspur or something.
While you can do a team based on brazilians (Real Madrid) you can do a champion team with no brazilians (Liverpool) or one Brazilian (Barcelona)
In the world there are lots of good players.
Why do we bring south american people here? because they provided a good quality/price relationship, and language/culture issues mainly. In Brazil or Argentina there are houndreds of players that are not brilliant, but can fill a gap in a first squad team correctly. But if you ask me given the money, they're perfectly replaceable with some eastern guys, spanish, or Italians. But the latter and the english and the germans are expensive, so many teams have bought a south american at some point.
and win the world cup, because you just think you're the best
