It’s his time.
A question Chelsea will need to answer this summer is what to do with Thibaut Courtois. The 20 year old Belgian has spent two successful seasons at Atletico Madrid and they are keen to extend his stay at the Vicente Calderon further. There are reports Chelsea want to loan the Belgian to a lower level EPL team but I believe that would be a waste of his time. If a loan is the intention then Atletico Madrid should be the destination and he will be able to experience CL football which would be of greater value. If he is to move to England the only reason should be to take over the No.1 jersey from Petr Cech. The Czech stopper is on the decline and in Thibaut, they have a ready-made replacement that in my eyes is already superior.
There is a conflict of interest in my opinion with Lollichon, Cech's GK Coach from Rennes days, doing scouting reports on Courtois. Cech will be in his best interests when it seems Courtois is ready to takeover. This is an assumption but comes from Chelsea's indecision on Courtois. When Cech came he was 22 and Cudicini 31, was on the decline. So I can't see why the same can't occur now.
So either Courtois returns to takeover or he spends 1 more season at Madrid, no more and plays CL football. This poses an issue, as if another keeper is bought Courtois will return to Chelsea with 3 keepers fighting for 1 place. I think it's time for COURTOIS.
There is the debate that Cech has many more years left. And there is sentiment which blinds supporters, but Cech is on the decline and not the Cech of the past. Seen sentiment overrule the obvious that Terry, Lampard are on the decline. Cech was 22 and Cudicini 31, so I cant see why the same cant occur with Courtois 21 and Cech 31 in the future. There is the debate about Courtois adapting to the Premier League and that rises from De Gea's adaptation and trouble with crosses. Courtois is bigger and more physical than De Gea and that won't be of any issue in my opinion.
On the Rise or On the Decline. Courtois should be integrated into the squad as soon as possible, as it is obvious he is greater than Cech was at that age and some may argue even at current age. The club comes first, so the better players should be played and not out of sentiment.
