Zoran Mamic won the cup with Al Ain from UAE. Anyway was looking at their wiki page out of interest and saw their whole coaching staff were Croatian.
I know the coach usually brings a few of his own guys but this looks excessive lol.

In fact before Mamic, Dalic was the coach, so they've had a Croatian coach since 2014. Should just rename the club Al Ainic.
