Anyway, the reason why Kane wasn't in the team isn't transfer related. He joined the club late so he still has some basic training to catch up to before actually playing.
If you ask me, It all falls back to the transfer issue cause I believe the reason why Kane returned back to the team late is cause of all this transfer talks surrounding him, tbh, I think Kane has already made up his mind and Spurs know this, though they are trying to keep him, but for now a final decision is yet to be made, thus they have to keep him out of the team, they wouldn't just say it that way, so it looks like it's down to 'professional' reasons that he missed today's game.
Having said that, I believe after today's loss to Spurs, City would make Kane's signing a priority, they seem to just be lacking the presence of a striker, Ferran Torres is anything but a marksman, and City really needs to get someone like Harry Kane whose job has always been to put balls at the back of the net.
