AFP - Fears over Euro 2012 being overshadowed by racist incidents returned on Friday after Netherlands captain Mark van Bommel said the team heard racist chanting during a public training session in the southern Polish city of Krakow.

Co-hosts Poland and Ukraine have already rejected claims that racist violence is rife at their football grounds, which has led to governments of some participating nations to warn travelling fans to be on their guard.

...The AC Milan midfielder added: "During the tournament, if any one of us is confronted with such a thing, we'll immediately go to the referee to ask him to intervene."
