Well things are very interesting now for Brazil with Dani Alves out of the world cup. Tite didn't rotate him much so no one really has too much experience. The obvious alternatives are Danilo (Man City) and Rafinha (Bayern Munich). Although I'm not too high on either of those. I do know the young star at AS Monaco, Fabinho can play RB as well as CDM and is excellent in defense, crossing and has size at RB that could come in handy at that position for aerial purposes. Alves was set to be their captain, and is the most decorated player trophy wise in the world with 38 total titles. Tough blow and hard to replace that kind of experience.
