Germany stars Leon Goretzka and Serge Gnabry have spoken out in condemnation of the racist abuse directed at teammates Leroy Sane and Ilkay Gundogan during Wednesday's draw with Serbia. "It is ridiculous to cheer on one player and insult another just because of their skin colour. Racism has no place in the stadium or anywhere else in society," Gnabry, 23, told German tabloid Bild. On Friday, police confirmed that three men had turned themselves in after another fan videoed them hurling racist abuse at Leroy Sane and Ilkay Gundogan. "It is really sad that things like this are happening in 2019, and it's important to raise your voice in a moment like that," said Gnabry. Gnabry's Germany and Bayern Munich teammate Leon Goretzka also called on fans to stand up to racism. "I watched the video, and the scenes that he describes made me really quite furious," said the midfielder. "I can only call on everyone to put people like that in their place."
