Whether it was because of the result, the way the game was played or simply the teams that were facing each other (any reason why you consider it bizarre).
For me the strangest/bizarre matches were the matches between national teams and clubs:
Boca Juniors Vs. México
Bayern Vs. Netherlands
Loma Negra (Argentine Club) Vs. URSS
Atlético Socoraba (Brazilian Club) Vs. North Korea
Tajikistan U-17 vs Audax U-20 in 2019
Yes, a bunch of youngsters from Central Asia faced a bunch of youngsters of an obscure Brazilian team from Osasco (a city in greater São Paulo).
The final score was 2-2.
But wait! There’s more!
After conceding a goal and a corner that resulted in a goal, the Tajik coach subbed the goalkeeper before halftime. The poor kid came out and cried on the bench, only to see his replacement pick up an injury and… the starter came back on and saved a penalty!
But wait! There’s more!
The assistant coach for Tajikistan was Musashi Mizushima, a Japanese former midfielder who became a pro and spent most of his career in Brazil, and eventually was an inspiration for the creation for the titular character and the anime Captain Tsubasa
