That was a different era when there wasn't many Asian players plying their trade in Europe, But even at that, how much income did that generate for celtic?
Can't remember anyone going on about how much celtic were bringing in from Japan because of Naka.
It might raise the profile of the club in Japan but that doesn't equate to increase revenue. Nakamura probably was the big winner out of it, same with Kyogo. It will raise his profile and he will get more sponsorship deals back home. Celtic might sell a few tops and a bed cover but not much else. When naka was here we had a couple of money spinning games lined up in Japan, maybe the club are planning that again
