Eren Jaeger, a teenager who just turned 16 this year, plays in the Portuguese Youth First Division. Recently, scouts recruited him to play for the Portugal national football team. He is truly the kind of prodigy seen once a decade.
It is funny and often noted that all other players in Portugal are 20 years old or older, and seeing a teenager at practice is amusing in a good way.
The Portugal squad players include (Reiner Braun, Jean Kirstein, Bertholdt Hoover, Connie Springer, Marco Bott, and 20 others, though these are the ones who talk to Eren the most).
It is quite funny because Eren is in his 4th year of high school and is sometimes pulled out of training because he has to go take a school exam.
