The term "Galactico" became known at the start of Florentino Perez's first period as president of Real Madrid.
But it originates from the 1950s, when President Santiago Bernabeu purchased stars such as Alfredo Di Stefano, Ferenc Puskas, Raymond Kopa, Jose Santamaria and Francisco Gento.
Real Madrid won five European Cups in that era, so Perez felt he was returning the club to its history and copying a winning model.
The phrase was used to illustrate the transfer policy of signing the most expensive and world-famous superstars around.
Like other clubs, Real Madrid paid millions for quality players under different presidents, but with Perez, these signings were incomparable.
The strategy was initially called Zidanes y Pavones, deriving from Zinedine Zidane and Francisco Pavon, a Real Madrid youth player.
The idea was to sign one major superstar per summer transfer window and promote youth players from within.
Some players were also regarded as part of the Galacticos, such as Roberto Carlos and Raul, though neither really qualified for the title.
The likes of Sami Khedira, Mesut Ozil, Angel di Maria, Fabio Coentrao, Isco and Asier Illarramendi have not been included in this list.
It could be argued that Ozil and di Maria were regarded as two of the best players in their leagues at the time of signing, but were they in the very top bracket for the world?
Even someone with a passing interest in football should have heard of the majority of these individual Galactico players.
Here they are ranked in order of success at Los Blancos.
