I actually think Courtois will benefit more from having a year on loan in the Premier League first, that's if i was gaffer anyway. Agree with you that we cannot lose the lad, he has all the attributes to be as good as Cech in his prime which would set us up nicely for the next 10 years! I actually think Petr may stay as 2nd choice, he has a great affiliation with the club and want better man to work closely with for Courtois than Cech?
Seen a lot of him watching Atletico this year, really little point in a loan at a Prem Club, he really is that good. What he needs is to come into settled defence whenever he arrives at Chelsea. That makes a big difference. De Gea didn't have that for the first season and the opening half of this season, made his development much trickier.
