Is words in quote(in English) the exact translation from his Spanish post to English? I was wondering what the "mythical ones of years ago" mean. Old players or some ancient creatures? Lol.
The translation is a bit clumsy, that's right. What is meant is "legends from back then". What he is talking about is a match between Barcelona and Real Madrid. The games between these two teams were very competitive at the beginning of the 2000s with legendary players like Ronaldhino, Xavi, Ronaldo, Zinedine Zidane and of course David Beckham.
Here is the article that explains a little more about the background why exactly these two teams and what the purpose of this game should be.
I see he is/was a goalkeeper. Probably old keeper? Guess I have heard that name longtime ago.
He is/was recognized as the greatest goal keeper for a very long time, some even consider him the greatest goal keeper of all times. If you are only very rudimentary interested in football you have already stumbled across his name 100%.
