03BA87DBFFCBFFD4FC833839FB316BF7.taxon	etymology	Etymology. In honour to Diego Armando Maradona (El Diego) the best world football player ever. In 1986 FIFA World Cup, Maradona, the “ People football player ”, redefined the football in less than five minutes (https: // edition. cnn. com / 2018 / 06 / 11 / football / world-cup-argentinaengland- 1986 - diego-maradona / index. html), first with the “ hand of God ” goal and then with “ the goal of the Century ”, related exquisitely by Victor Hugo Morales. In words of Emir Kusturica (https: // www. youtube. com / watch? v = O 8 G 9 ytZgbM) “ that match was maybe the first and the last time that there was justice in the world ”. He inspired the people and many popular artistic expressions via his Maradonian way.	en	PETRULEVIČIUS, JULIÁN F.
