The European Club Association says Bayern Munich's 3.1 million euros ($3.81 million) payment was the biggest share from UEFA's 100 million euros ($122.83 million) club compensation fund for releasing players to EURO 2012.
Bayern topped the table of about 575 clubs being paid after it sent 12 players, including eight of Germany's squad that reached the semi-finals, with five different teams to EURO 2012. UEFA also gave clubs daily-rate payments for releasing players to qualifying matches in 2010 and 2011.
The ECA said Real Madrid received almost 3 million euros ($3.69 million). Madrid sent 11 players to Poland and Ukraine, including five from eventual champion Spain and three from semi-finalist Portugal.
Barcelona received 2.21 million euros ($2.71 million), Manchester City earned 2.07 million euros ($2.54 million) and Juventus collected 2.02 million euros ($2.48 million).
Gibraltar, the tiny British overseas territory boasting just one professional player, will take part in the EURO 2016 qualifying campaign after gaining UEFA membership - but will be kept apart from Spain.
