We have a long standing brotherhood with Olympiakos, since the 1980's. We are both of orthodox christian descent, and both play in Red & White. Also, the Serbian and Greek culture is very similar. Feel free to research greater details but these are the main reasons we became friends, and this friendship has grown ever since. Sometimes our supporters will attend Olympiakos matches, and they sometimes come to our matches. The link and friendship is very strong and we call ourselves "Orthodox Brothers". Spartak Moscow is also in our friendship circle, it is consisting of Red Star, Olympiakos, and Spartak Moscow. But we would consider to be closest to Olympiakos.
Here is our display before our Champions League group stage game on Match Day 2.
The TIFO was of both our club badges in unison, and the message below reads "Let today win the one in better mood - We will be brothers forever in evil and good"
