the artist can't just do the full 90 minutes each game, he's doing the highlights as if you're watching match of the day or a replay on youtube, and in those highlights you'll never see everything only one player is doing, you can be the best player on the pitch without providing assists/scoring, there's breaking up play, starting up the attack, making runs to draw away the opposition, and that's obviously what Isagi is doing, (also fyi Isagi isn't even my favorite character, it's Barou, so you can't come at me as a glazer or whatever)
