He is not that short. He is 1.81m but yeah he shorter than the average CBs in the top 5 leagues. He can be converted into a DM imo, his ball-playing skills are not that bad. Its better for Japan anyway, Japan's DM problem is more serious than the CBs. At least Japan has the likes of Nakatani, Shoji and Ueda to fall on and Yoshida might still be available in the Qatar WC.
