Please, could anyone indicate to me any good sport manga? I only know like seven and I rea...

I'm also new at this, so I can only refer you to the ones I've seen and know of... But they may be the same you know xD Kuroko no basket, slam dunk, prince of tennis, Yowamushi pedal, free (but that's anime lol) ookiku furikabutte, diamond no ace... Can't remember more (￣∇￣") but you can get in here http://www.mangago.zone/genre/Sports/ and see the rating of manga ヾ(❀╹◡╹)ﾉ~

What about "Eyeshield 21" I really loved it. It's about American Football.

http://www.mangago.zone/read-manga/15_meisetsu_kougyou_koukou_rugby_bu/ I recommend this, one of my fave,

major is pretty good if u like baseball. one outs too

for major, watch the anime ver.

Ookiku furikabutte. Baseball supa great(๑•ㅂ•)و✧

If you don't mind it being more on the psychological side and missing a few chapters, One Outs is a total masterpiece in my eyes
