Real Madrid veteran Thibaut Courtois is one of the best goalkeepers in world football, and it is close to impossible to dispute that fact.
The Belgian star has been a mainstay for Real Madrid for a long time now and is currently one of the leaders of the dressing room.
Heading into the new season, his age seems to be just a number and the player will remain the number one choice of the manager.
If recent seasons have shown anything, however, it is that having a solid backup goalkeeper is essential. As Courtois ages, fitness no longer remains on his side and there are often situations where the club faces the need to have a reliable plan B.
Andriy Lunin has been that player in recent years.
