When Brazil battered Portugal in a friendly, Anderson told Ronaldo: ‘Next time we’ll play our fifth team to give you a chance.’ Ronaldo was not amused. That’s the kind of country Brazil is. I love that story about the competition in Rio to unearth new No. 10s and thousands turning up. One boy travelled for 22 hours on a bus. It’s a massive country, with talent everywhere.
What does mean? the underlined words...
I don't know much about football (soccer), but I understand it to mean that there was a competition held in Rio to identify talented young footballers who might become professionals, and eventually play with the number 10 on their shirts. I believe the number 10 often identifies the wearer as being the team's main "striker", and hence a very important individual. It would seem that thousands of hopeful candidates travelled from all over Brazil to take part in the competition.
I'm not a teacher of English, but I have spoken it for (almost) all of my life....

It's a match in which the result is unimportant. It is not part of a tournament or a league. No points are awarded to either team based on the final score. It's almost a practice match.
"Exhibition game" we would call it here.
