Well explained 777.
There used to be saying when i was a child, and it kinda still goes on for years and years...
Besiktas always beats Fenerbahce.
Fenerbahce always beats Galatasaray.
Galatasaray always beats Besiktas.
And this explains the situation for last 20~ years.
As a Besiktas fan, i can say that Besiktas hate against Galatasaray isn't low either, in fact prior Galatasaray games, people keeps saying that our actual enemy is Galatasaray because of the incident in 1992/93 season. (Where Besiktas accuses Galatasaray to fix games to win the title)
And Bursaspor thing is just a disgrace...
For 7 years long, Federation did not let those teams fans to go away games against each other, and they finally opened doors last year, letting Bursaspor fans to come to Istanbul. And see what happened just outside the stadium:
6 months later Besiktas was invited to Bursa and Bursaspor fans surrounded the hotel Besiktas PLAYERS were residing...
The police did not let Besiktas fans enter the city of Bursa and the game was cancelled (3-0 for Besiktas).
And now, the Federation stepped back, and they announced that they won't let any away fans in Besiktas-Bursa games this season... Besiktas will play against Bursaspor in Bursa on Thursday (2 days later), and there won't be any Besiktas fans. I just hope nothing bad happens to our players.
