The image of an elite professional footballer playing with holes in his boots is not one that you come across all too often, but that was the case of Bayern Munich's Mats Hummels at Signal Iduna Park on Saturday.
The Germany defender left people scratching their heads during Bayern's Bundesliga victory over his former club, Borussia Dortmund, when it became apparent that his big toes were poking out of his footwear.
Hummels: "Maybe I've created a new model of boots..."
Asked post-match about the curious state of his Adidas boots, Hummels revealed that he had himself cut out the holes in a bid to ease the effects of a foot problem.
"My toes are sore and I wanted to avoid feeling any pressure on them," he explained, quipping: "Maybe I've created a new model of boots for the future."
Robben, Lewandowski and Alaba goals win it for Bayern
Goals by Arjen Robben, Robert Lewandowski and David Alaba saw Bayern win 3-1 in 'Der Klassiker' to go four points clear at the top of the German league.
