This summer, Zenit St. Petersburg signed Hulk and Axel Witsel, who are of mixed ethnicity. They are among the darkest-skinned players who have ever suited up for the club, and they are not liked by all supporters.
Presented without any further commentary, a quote from a letter sent by Landscrona, the largest supporters group for Zenit St. Petersburg, to the club itself. Via The Guardian:
"We're not racists but we see the absence of black players at Zenit as an important tradition."
