How fast are professional soccer players supposed to be?

I love soccer and I want to become a pro like my idol Ronaldinho Gaucho.I want to know these two questions.
1. How quick do pro soccer players (midfielders and forwards) need to finish a mile run.I heard they need to at least run for and hour but I don't know how fast mph they need to run it.
2. How long are pro soccer players (midfielders and forwards) need to run on the treadmill.
