He did 2 major errors in the last game.
No, he didn't. You also have to consider what would have happened had he not come out at all. Anyways, he does it at such a crazy high frequency with an incredible success rate that it doesn't even matter any more when he goofs up once in a while. He prevented far more goal scoring opportunities in the meantime.
Should have been red carded and almost suffered a goal. He has good press. If it was Casillas everyone would lose their minds but Neuer is a pretty boy.
The press is the only reason Casillas is considered a great goal keeper.
How that softie won so many awards will always puzzle me. Real Madrid since young. Spain's darling. Never on the level of the likes of Buffon, Schmeichel, Kahn, etc.
