It seems fairly unlikely it’s based on anything other than World Cup performances. A quick look at his Wikipedia suggests that for British viewers, the only time he could possibly have been seen other than playing for Brazil is if he featured for Fiorentina or Pescara on one of the early C4 Football Italia’s between 1992 and 93. After that he went to Stuttgart for a couple of seasons. I can’t recall any broadcasters showing Bundesliga games back then. Sky Sports was still at 2 channels, and aside from that there was only Eurosport.Be interesting to see how much of Dunga he's actually seen as well.
Other than his world cup appearances, I'd expect its not many.
Dunga was widely slated for his performances at Italia 90, but to be fair, he was one of the better Brazilian players of 1994. One of the worst sides to win a World Cup, and few will argue with that. But other than being captain, he was by no means the most memorable or stand out player in a side which also had the likes of Romario, Leonardo and Bebeto. As for 1998, well, you would have had to not even bother watching it at all to put him, or any other midfielder for that matter, ahead of Zidane.
