Not sure if you know this, but Neuer was not supposed to be Germany's keeper in 2010 world cup. After Enke committed suicide, Low tried both him and Adler for a few matches to decide who would get the starting spot for the WC and he actually decided that it would be Adler over Neuer, but he suffered a back injury IIRC a couple of weeks before the WC and Neuer ended up as the first choice keeper as a result. Neuer is definitely capable of the incredible, but he's also prone to the absolutely stupid. He reminds me of Lehman in a way. Very erratic and unpredictable which isn't exactly things you want your keeper to be. I honestly still prefer Adler and I think that Ter-Stegen should be the future keeper for the German NT.
