1) His name is, and has always been, “Soñora”.
You got the tilde ~ over the n, ñ, but his name is pronounced: [sewn-YORE-ah]
Not that the gringo announcers ever pronounce it that way.
2) Soñora came up through the Boca Jrs youth system and then eventually played some for them. That is one of the two biggest, most prestigious youth Academies in the western hemisphere (River Plate of Argentina being the other… sorry Brazil) before making his move just a bit south, across the Riachuela, to Independiente (de Avellaneda).
3) Independiente (de Avellaneda) is one of the “Big 5” clubs of Argentine soccer.
From Wiki:
In international club football competitions, Independiente has won a total of 21 titles, with 18 of them organised by CONMEBOL and other associations. Independiente's achievements include a record of seven Copa Libertadores won, being the only club to win four finals in a row, between 1972 and 1975. The club has won the Copa Interamericana three times, the Supercopa Sudamericana twice, the Recopa Sudamericana once, the Intercontinental Cup twice (1973 and 1984), and the Copa Sudamericana twice, in 2010 and 2017. The 2018 Suruga Bank Championship was its most recent achievement.
These achievements led the team to adopt the nickname of Rey de Copas (King of Cups) after they conquered its 12th international title, the first team in the world to do so, in reference to the Spanish playing cards' highest number. After winning the 1984 Intercontinental Cup against Liverpool F.C. in Japan, Independiente won the first confrontation involving Argentine and British teams after the Falklands War, a triumph that was celebrated by all Argentines and gave the team the motto of Orgullo Nacional (National Pride).
IN SUMMARY [TLDR]:
Soñora’s blood line, academy development, and Argentine resume looks excellent, which is in stark contrast to his play on the pitch.
I never watched him play in Argentina, but he started at the #10 off-and-on for a couple of years at one of the biggest clubs in the country. That alone gives him a better resume than most players on the USMNT’s Gold Cup roster. That said, he plays like shit against CONCACAF competition.
