When the Israeli football team Beitar Jerusalem signed two Chechen players it broke a long-established tradition of not signing Arabs or Muslims.
The recruitment of Zaur Sadaev and Gabriel Kadiev - both Muslims - prompted some fans to display racist banners and the club's office was destroyed in a suspected arson attack.
