Only 1 or 2 of the Croatian coaches worked in UAE. I'm talking Arab world in general where with the exception of Dragan Talajic and Rodion Gacanin (Who is now called Hamid by the Arabs

) all the others left after less than a season. And most of those actually had a good career before and after that (Ilija Loncarevic, Ivic, Kranjcar, Begovic, Bonacic, Juricic, Mirko Jozic, Tucak, Mato Stankovic, Peruzovic, Matosic, Radojcic, Katalinic, Buljan etc).
I don't know what they mean by "the air". In that video I posted above Kranjcar said that "there was something in the air" that he couldn't stand in UAE.
