Real Madrid president Florentino Perez remains concerned over moving for Chelsea ace Eden Hazard.

While he is prepared to meet the demand of coach Zinedine Zidane in signing Hazard, Mundo Deportivo says Florentino is doing so reluctantly.

The president has concerns that Hazard's arrival could stunt the progress of Vinicius Junior, a player he personally pursued 18 months ago.

Florentino sees the Brazilian youngster as a future Real star and is eager for him to continue his steady development next season.

Chelsea and Florentino are currently haggling over a fee for Hazard in the region of €100m.
