Former Brazil Under-20 coach Ney Franco believes that Real Madrid star Casemiro has developed into one of the best defensive midfielders in the world, and credits his time at Porto for helping the 26-year-old adapt to life in Europe.
Having come up with Brazilian side Sao Paulo, the midfielder earned a move to Real Madrid in 2013, but was sent out on loan to the Portuguese side in 2014 after failing to find his way into the Madrid first team.
Casemiro returned to Madrid in June of 2015 and has developed into an integral part of Zinedine Zidane's squad.
