France coach Didier Deschamps admits he is worried about Alphonse Areola's move to Real Madrid.
Areola has moved on-loan from PSG - effectively as Thibaut Courtois' backup.
Deschamps stated: "Whether they are goalkeepers or on-field players, it is better that they have minutes.
"If you stop playing, it can become problematic."
Asked directly about Areola, Deschamps added: "For the next October call we will see how much he has played and we will decide."
