I don't see anything strange. They really look like the best team right now, and a 100% win rate seems normal for a team like that. The problem is how they became the best team.
If they keep this squad together, they don't have to worry about relegation - they'll be back the following year (if they get relegated to the Championship, of course).
Manchester City is very far from relegation, that's their least problem now. I can't remember if they have ever been relegated in the last 20 years. They have been consistent before now and even after this, they are going to remain one of the best. Regardless, they will have to answer to the charges, but upon all of this, if the result doesn't come with reducing of points, the players will not have nothing to fear, only the club will bear the financial burden.
I have seen some videos of how some people said that the Manchester City owners are very influential, they have money to pay up that is why they did they did. They know what they got their self into, they know their lawyers are going to fight this. If they could get away from UEFA, Premier League wouldn't be that headache that will stop them. I'm sure they are going to be fine money and the world will move on like nothing happened.
The latest information I've heard is that they'll get a 60–70 point deduction. The idea is that this would be enough to send them down. But watching them play, I think it might not be enough. At the same time, it could motivate the players to play even better than they do now.
Money matters, but in my view the punishment should be comprehensive: relegation, stripping them of titles, and financial penalties. At the same time, I'm sure the punishment will end up being much softer.
