#1 Sven Ulreich
The last three matches before Heynckes' arrival ended winless for Bayern Munich, as they conceded a total of seven goals. Not something you expect from a team like Munich and a goalkeeper like Neuer. But wait, it wasn't Neuer in front of goal. Instead, it was his back-up, Sven Ulreich.
A back-up for Manuel Neuer, that's what Ulreich's role was in Bayern. In such a star-studded squad, hardly anyone had any expectations from him. Ulreich's only Champion's League experience had been against Rostov and Dinamo Zagreb. But all of a sudden, he was supposed to stop attackers like Cavani, Mbappe and Neymar.
Expectedly, he faltered, giving away easy goals. Criticism arrived from all directions. In comes Jupp Heynckes with a small but much-needed reminder. A reminder of Maier, Pfaff, Kahn, Neuer and the great lineage of goalkeepers he was part of. A reminder that he represented a club that believed in facing problems rather than running away from them.
With a sudden burst of confidence, Ulreich started making crucial saves, performed better one-on-one and even won his team a penalty-shootout against RB Leipzig. His drastic transformation was validated by his composure against PSG's holy trinity in the return fixture. Deservingly, he was voted as the Fan's Player of the Month, ahead of Joshua Kimmich and Javi Martinez.
