Courtois should be patient a little bit more, it's Cech that he will replace, it won't happen next year as well i can see. But yeah it's so obvious Chelsea will never let him go, one of the best goalkeepers in the world and probably the best young goalkeeper, as i said before he can easily be one of the top 5. How can a team like Chelsea sell one player that is the solution for many years in the future just because Cech is in his way, he is for the moment, but won't be in some time. Courtois just has to wait, Chelsea surely wants to keep him so there isn't any problem unless he doesn't want to be loaned over and over again until he's finally a starter there.
