SPI odds to go through: Barcelona 82 percent; Atletico 18 percent. This meeting between the two Spanish giants is a replay of the 2013-14 quarterfinal, when Atletico came out on top, and the teams have faced each other many times in crunch matches since.
Treaty of Tordesillas. Treaty negotiated by the pope in 1494 to resolve the territorial claims of Spain and Portugal. The Portuguese colonized Brazil under the terms of the Treaty of Tordesillas, a 1494 agreement dividing the Americas between Spain and Portugal.
The treaty of tordesillas was a negotiation of a previous papal bull (Papal bulls were decrees issued by the Catholic Church which allowed the leaders/crown of a country to do something). This papal bull was issued in 1493 by Pope Alexander 6th and it drew a line across the globe, sharing the land which Portugal and Spain could colonize and claim.
