Due to strict UEFA rules the Croatian national football team had to wear their blue jerseys in their opening three group matches against Turkey, the Czech Republic and Spain. As these three group opponents of Croatia had red and white on their jerseys, UEFA made a strict decision before the tournament that the Croatian football players would have to play in their blue jerseys in order to avoid clashes.
The Croatian red and white checkerboard design, which has become famous throughout the world and even has inspired Marc Jacobs for his new collection of slip up shoes, was voted the best looking jersey before the championship even started. As the Portuguese footballers will wear their green jerseys in the match against Croatia on the 25th of June at the Bollaert-Delelis stadium in Lens the Croatian players will finally have the opportunity to run out on the field wearing their jerseys in the red and white cubes.
Apart from the UEFA's strict rules regarding the Croatian jersey this football organization didn't apply such rules to the Croatian player Vedran Corluka, exactly the opposite.
After having injured his head in the opening match against Turkey the Croatian defender donned a water polo cap in the match against the Czechs in order to prevent opening up of his head wound. In the match against Spain Corluka run out on the field wearing the water polo cap again after UEFA gave him the green light that it was all right for him to play with his cap on. UEFA only advised him to remove the ear protectors from the cap but anyway Corluka made history as the first player ever to play in a water polo cap.
UEFA asked Corluka a permission to take a photo of the Croatian defender wearing water polo cap so it could be kept in the UEFA's museum as a part of the football history.
