Courtois should really be our no.1 from next season, or at least be given that chance. Cech is obviously still a top keeper, not as good as he was in earlier seasons, but Courtois looks exceptional. Mourinho will play it safe and offload Courtois, stick with Cech because he is reliable, experienced and a leader. I know it isn't done with keepers but we could rotate them each game, whoever performs best by January/the end of the season remains first choice. Courtois has done as well, or better then could be expected, you have to question the signing if he isn't in our plans.
