Despite many prejudices around sports anime, both Eyeshield 21 and Area no Kishi are worth the watch; they're both about personal development as well as sports-wise. It's not only about either soccer or football, they also hold humour and lots of drama which is, in my opinion, essential for a good anime series.
I was never a fan of sports myself, but the way these two animes portray the sports makes you want to watch more. In Area no Kishi's case you can't help but feel sorry for Kakeru because of all the tough times he's going through with his brother, his dreams and his own fears.
Eyeshield 21 is more humourous, but does also stick to a more serious pattern when it really counts. Sena is the heldback, small boy who's been pushed around all his life and finally overcomes all the trials he's been a victim to. The humour in it, is how the Team Captain treats him and how tough he's practicing to become an international player.
Both animes circulate around dreams and overcoming yourself or your fears. Even for a person who's not into the sport-kind of anime, these series will not disappoint, I speak of experience. And with all the problems both main characters face, your dislike for the sport quickly goes away.
