Thibaut Courtois is a member of the Belgian golden generation, though he is a few steps behind Simon Mignolet.
Keep in mind, Courtois is four years younger than Mignolet.
Courtois was originally a left back but was tried out as goalkeeper, and at 16 years of age, he made his professional debut.
In terms of persona, he reminds me of Wojciech Szczęsny. He just says what he says, even if sometimes it's best to just bite the tongue.
Here is what Courtois said about Petr Čech:
The Chelsea goalkeeping coach (Christophe Lollichon) said to me that he does not know how long he [Čech] can continue to play at the highest level. He has problems with his knees and with his back.
I guess it's easier to look past what he says because he is a fantastic prospect in goals.
