Abusive Ron-Robert Zieler chants at Cologne intolerable - Lukas Podolski
Former Cologne star Lukas Podolski has hit out at supporters who verbally abused Stuttgart goalkeeper Ron-Robert Zieler as the club identified two of them, who now face bans.
Ex-Leicester keeper Zieler, born in Cologne, was targeted by a section of the home fans during the second half of Stuttgart's 3-2 away win on Sunday.
Some supporters, one of whom appeared to be using a megaphone, shouted sentences including: "Zieler, why don't you kill yourself?" and "Your mother is related to [former Germany keeper Robert] Enke," with the shouts clearly audible on TV.
Former Germany keeper Enke took his own life in 2009, having suffered from depression for many years.
And speaking to reporters following a J-League match for Vissel Kobe, former Cologne star Podolski said: "As pros we must live with insults. But what happened in Cologne, referring to Enke, is unacceptable. We can't tolerate this."
Cologne said on their official website that they have started banning procedures against two people, who could now face a stadium ban. "Neither the fans nor the ultras are responsible for the chants," the club said.
German FA (DFB) president Reinhard Grindel called for a clampdown as the organisation opened an investigation into what happened.
