I hope Cech keeps a clean sheet. I really do. His acquisition has underlined your success this year - and he's embodied a change in your fortunes. He is so professional and seasoned, very experienced and calm, and has really shone ever since arriving (bar perhaps that opening game and the gaffe to allow West Ham a victory).
Obviously, if Mourinho had his way, he'd have gone nowhere. But it's good he did - because a goalkeeper like him doesn't deserve to be playing second fiddle.
Although, of course, Courtois' lengthy spell on the sidelines would have meant he was vital during the early stages of Chelsea's campaign.
