@Alexvinssi. Yeah, I forgot to add him too but as he was not in the last chapters, I forgot about it. But in the case of Sakuraba at least, in addition to use him like a come dy relief, the author put a kind of restriction, making him miss goals (because so far, and of course I say so far, he never scored in important games apart for the PK).
Actually, I appreciated the fact that he missed the second goal in the previous games and that the author uses his "overpower" as a bait for motivating Ryu. But, I am so happy that the author did not make him the bad guy in the opponent team. Anyway, i am sure that if they start one day to face youth club teams, there will be people able to handle Sakuraba.
