Karim Benzema was photographed showing the flag of Atletico while Koke hid it behind his body during the ceremony with the referee before the first whistle, where the captains pose with the flags of the opposing teams.
In the most recent Spanish Super Cup final, which was played in Saudi Arabia, Benzema also displayed Barcelona's flag, whereas Busquets did not do the same for Real Madrid.
It's a classy gesture by our captain, which deserves to be applauded of course.
