Celtic fans needed some convincing before they got behind new manager Ange Postecoglou last month after he joined the club from Yokohama F. Marinos.

The Australian¡¯s first major signing, Vissel Kobe talisman Kyogo Furuhashi, hasn¡¯t needed nearly as much time to win over the green-and-white faithful, and for good reason.

Friday¡¯s announcement of the 26-year-old attacker¡¯s transfer arrived like a bolt from the blue ¡ª a description Celtic fans might object to on moral grounds, even if it represents a welcome relief from the weeks of rumors that usually foretell the club¡¯s signings. Yet it carries tremendous upside for all involved and may be one of the most important pieces of business involving a J. Leaguer that we see this summer.
