Until 2016. There's many possibilities for the future of Courtois, selling him, one of the brightest young keepers for 20mil to a PL rival is not one of them. I can see him going back to Chelsea next season and competing with Cech, who has been great but also seems to not have a body which can keep playing on the highest level until his late 30's, things can change quickly just look at Cudicini going from player of the year awards to being a fairly young Cechs reserve under Mou.
I love how everyone seems to think we'll just up and sell our best players or brightest prospects (mata, Luiz, courtois) and tries to sell for us to other Prem teams despite us having no track record for doing so!
Mou wanted him at Chelsea this season, he said he wanted week in week out game time which mou understood. Mou then wanted to loan him to a prem team but courtois was happy at AM and they are in CL so we let him go back there.
Cech won't be with us for another decade. He's a fantastic keeper and great guy, I wonder if his previous head injury might see him retire earlier though.
TC will go to a prem club on loan next season but I see no reason why he won't sign a new deal and stay with us. If he's patient he's got that no 1 spot wrapped up for 10/15 years.
Also we'd never sell to Barce either because they're incapable of paying the asking price and we'd never deal with them regardless of mou's history with them.
