Mario Gotze's World Cup-winning left boot has been auctioned off for charity, raising an astonishing €2m.

The midfielder donated his Nike boot, the very same one he scored the winning goal with in the World Cup final in July, to raise funds for German charity 'A Heart for Children'.

It was the left foot of Gotze that struck the crucial goal in the 113th-minute for Germany in their 1-0 triumph over Argentina at the Maracana in Rio.

Gotze never cleaned the historic boot, which raised €2m (£1.6m) in a gala for the German charity.

"I have never washed the boot. It is still in the same condition as it was in Rio, when I left the stadium with it," the Bayern Munich star told Bild.
