Bayern Munich goalkeeper Manuel Neuer, widely considered the best in the world at his position, is a doubt for the Champions League quarter-final first leg against Real Madrid.

The Bundesliga leaders have announced that the 31-year-old Germany goalkeeper injured his left foot in training on Wednesday, with club doctor Markus Walther performing a small operation that the club says "went optimally."

Neuer, who was named the planet's best keeper by FifPro in 2016, will miss two games for sure and is touch-and-go to recover in time for the crunch continental clash at the Allianz Arena.
