As popular as you are, probably
I mean your comment is nearly as bad as wait until he has to play on a cold Tuesday night at Stoke.
I expect Kyogo to tire near January because essentially he was already a good way into his season in Japan and then was thrown straight in at Celtic. He hit the ground running because he was match fit but he will have played a lot of games by January plus had an injury and the pitches will start to get heavier. That also makes the style of football more different because our pitches get pretty shit by January and the ball will probably spend even more time in the air which will not be ideal for someone of his stature.
I think for the young boy it won't be about the pitches, it will be about pressure and handling the pressure to win all the time and like now if their form continues that pressure will intensify 10 fold.
