Celtic have started their January sales early with Japanese champions Vissel Kobe agreeing a 870,000 deal to sign forgotten on loan midfielder Yosuke Ideguchi, according to reports in his homeland.

Okunki has scored four goals and provided two assists in the Bundesliga 2 across 15 appearances so far this season. It is suggested that the Scottish champions are yet to make a formal approach for the Japanese player but he is said to be one of their top targets for the upcoming January transfer window.
