Nationalities and changes of stereotypes

After we signed Fernandinho, I was thinking about prominent Brazilian football players. So we have him, who supposedly is somewhat of a never ending, always running, powerhouse. And he passes the ball as well. Chelsea have Ramires. Tottenham have Sandro. It seems Brazil, who at least in Sweden were thought of as technical and fast but pretty undisciplined tactically, are providing more.... for lack of vocabulary, harder players and not as many "samba"-players as they used to. The same thing is happening with players from the African continent. If you had an african player in a Swedish team in the eighties or nineties, they were there to provide flair and not graft. But fast forward to the first ten years of this milennia and for a while, it seemed that each top club had a physical african, sub-saharan it should be added, player bossing their midfield.
On the other side of border from Brazil, the argentinians on the other hand still provide players who will play their hart out for 90 minutes but who are not as brutal as they used to be. I'm not too familiar with Argentinian football history, but it seems that they've become more like Brazil used to be and are now churning out top strikers and attacking players but perhaps not so many physically present midfielders or centre backs.
Now these are all stereotypes and they are never true, they never where and they never will be, but am I the only one who's seeing changes in what type of players that different countries and regions of the world are producing nowadays compared with how it used to be like 20-30 years ago.
Just a thought, I'm intested to see if anyone else has thought about this recently.
