It's not easy to win a Goalkeeper of the Year award when you rarely ever have to do anything. However, Manuel Neuer has shown over the course of his Bayern Munich career that, "It's not the number of saves you make. It's the quality saves you make."
During Pep Guardiola's first two seasons at Bayern, Neuer fully evolved into what became known as the "Sweeper Keeper". For the majority of most matches, he was standing close to midfield for the sheer purpose of stopping opposition counterattacks. During this season, this wasn't a necessary job for Neuer, as Guardiola's adjustments and the ever-improving defense put Neuer into a far more "observer" role than ever before.
Neuer remained the "sure thing" at the back for Bayern throughout the entirety of the season. With Holger Badstuber, Jerome Boateng, Medhi Benatia, and Javi Martinez all missing extensive time due to injuries, Guardiola was forced to put 21 year old never-been-a-centerback-before Joshua Kimmich into the role. The team didn't miss a beat.
At all times, those defenders could look at the goal and see the world's best standing there, ready to save the day at a moment's notice.
