I usually don't read Sports Mangas because it doesn't get me as hyped unlike Animes. But boy, does this manga gets me soooo hyped up. I have zero knowledge of football/soccer and yet it's very easy of understand and not at all confusing. The storyline is interesting, though less humorous unlike other sport animes (Haikyuu!!, for example) but still very well-written. None of the characters are boring at all. I find myself loving all these characters. The art is amazing as well, I never get tired of looking at it. I honestly don't want to recklessly give a 10 but I can't think of any score lower for this one.
If this ever becomes an anime (I really hope so!) it would definitely become a big hit, no doubt.
Really worth the read, give it a try if you haven't done so!
