Real Madrid are determined to look for competition for Marcelo from someone outside the club. Mendy, who has apparently passed his medical, seems to be the man chosen.
Zidane knows that he needs a reliable left back to make Marcelo fight hard for his place. The Brazilian has not had his best season at Real Madrid.
Marcelo has had various competitors during the 13 seasons he has been at Real Madrid., but no one has been able take the spot off him. In total, Roberto Carlos' successor has played 486 games.
If Ferland Mendy's arrival is confirmed, Marcelo could drop to the bench next season. It will all depends on Zidane's decision.
