Area no Kishi and Days are sports manga that tells the story of a young man who gets into soccer. Both series' main male protagonist starts out as rookies, a sharp contrast to another main male protagonist who is considered a prodigy. As the story progresses, we see the rookie develop their skills through experiences. There is also some romance subplot in both series as well and drama.
In both series, the main protagonist becomes interested in a sport but starts off as an underdog. They work their way up and faces against skilled teams as they try to prove themselves. There's also similarity between the main protagonists especially in their personalities.
Days is basically like a football / soccer version of Beck. Very similar vibes. Even the characters bear similarities in looks and how they interract with the story. If you like stories where characters progress then both might be for you.
