To be fair though, he hasn't been playing this well the last seasons. This season he is just on fire and in this form I wouldn't take any other keeper over him. And although always having been a top 10 keeper in previous seasons, there were keepers better than him (in before someone says "you're not rating how important his ability to the ball with his feet is".)
And despite it being sad that he is leaving, I am extremely happy that he is playing so well in his last season so he finally gets the recognition from the fans because he has been hugely underrated and gotten more shit than he deserves.
