Euro 2012: no Uefa investigation into alleged racist abuse towards black Holland players during training in Krakow The problems reportedly occurred when players began Wednesday's training session by doing laps of the pitch, only to be greeted at one end of the stadium by monkey noises and loud jeers. The abuse was said to be bad enough for the squad to move their equipment and training drills as far away as possible from that area. "At least now we know what we can encounter," Van Marwijk was reported to say sarcastically. Very atmospheric. Van Bommel, who along with his team-mates visited the former Nazi death camp at Auschwitz yesterday, was quoted as saying: "It is a real disgrace, especially after getting back from Auschwitz, that you are confronted with this. We will take it up with Uefa and, if it happens at a match, we will talk to the referee and ask him to take us off the field. He added: "You need to open your ears. If you did hear it, and don't want to hear it, that is even worse. Holland were due to travel to Kharkiv, Ukraine, today where they will hold a press conference ahead of their Euro 2012 Group B opener against Denmark tomorrow. There were always fears over racism at this summer's tournament, with BBC's Panorama programme last week highlighting the problem at Krakow's two major clubs, Wisla and Cracovia, as well as in Ukraine. Uefa president Michel Platini said on Wednesday referees would halt or even abandon matches if there was serious racism from the stands during Euro 2012. But he also warned that any player who walked off the pitch in protest - as Italy's Mario Balotelli had threatened to do - would be yellow-carded. The families of two of England's black players, Alex Oxlade-Chamberlain and Theo Walcott, have already decided against travelling to the tournament because of the potential problems.
