Celtic star Tomoki Iwata accepts he will have to raise his game to reach the high standards of Callum McGregor after admitting he regards the Hoops captain on a far higher level than him.
The Japanese ace joined Celtic in the last transfer window and Ange Postecoglou has opted to use him so far in a central midfield role, although he has also played as a central defender and a full back for former club Yokohama F.Marinos under the current Parkhead manager.
And Iwata admits even his limited time so far at Celtic has shown him he needs to get up to speed quickly if he is to play next to Hoops captain McGregor. Iwata, in an interview in his homeland, said: "I knew if I wanted to play in European football, I would have to play as a holding midfielder. That's where the manager used me at Yokohama.
