The former Netherlands international has stressed that the co-host nation of Euro 2012 is fighting ethnic prejudices, and that he has a positive impression of the country
It has been reported that members of the Netherlands squad were subjected to monkey chants during training in Krakow, while the Czech Republic's Theodor Gebre Selassie was allegedly verbally abused during his side's defeat to Russia in Wroclaw on Friday.
Nevertheless, the former Netherlands star's numerous visits to the country have left him with nothing but a positive impression of the host nation.
"I've been to Poland many times and I have very positive impressions," Gullit, a Respect Diversity ambassador, told reporters.
"I know that Poland has done much to eliminate racist behaviour from stadiums. Therefore, I appeal directly to fans: have fun, and let the football be the only winner."
