Acknoledgement of the first mistake

The organization finally admitted its first mistake (one of many) in the tournament.
The error happened on the penultimate group day at the EURO 2016 game between Croatia and Spain, where penalty was given for the European champions. Seeing how Danijel Subasic left the goal-line prematurely, UEFA's referee director Pierluigi Collina said that Sergio Ramos should have re-taken the penalty (which was saved). According to penalty regulations the goalkeeper have to remain on the line until the ball is touched. 'It was a mistake, unfortunately it happens. It was one single incident where the goalkeeper moved before the penalty kick was taken and it was not spotted by the referee's team.' said the famous Italian.
To sum up, the referee director said that 12 referees were chosen for the knockout stages, including the 'sinner' Bjorn Kuipers (who officiated the above mentioned game).
