Asian fans racially abused in Euro 2012 stadium
Sol Campbell has told the BBC's Panorama that Euro 2012 should not have been awarded to Poland and Ukraine, due to the racist and violent attitudes of some supporters.
The former England captain advised fans to "stay home, watch it on TV... don't even risk it."
UEFA, European football's governing body, have defended their decision, and said awarding the tournament to the two nations was an opportunity to improve their image and tackle social challenges.
Chris Rogers attended one match in Ukraine where he saw Asian men being kicked and punched, despite supporting the home team.
