If we look at the final score, then we will conclude that their game is bad. But this is preseason where many people do not take games like this seriously, and so is the Chelsea game. On the other hand, it is natural to feel a bit worried about Chelsea, and in fact this can be felt even in the last few seasons. I personally would not be so quick to conclude that their game is bad, but I would wait until the league starts.
Statistically, their game is actually good, but if we comment on this game, then their defense needs to be improved a lot, even though now we are not really seeing their best performance. Because they could be experimenting without caring about the results of the game, the most important thing is that they can evaluate everything after this preseason game.
I do get that they are not going to take it seriously, but when you are not taking it seriously that means you do not run that much, or you do nto chase balls, or you do not cover your position like you should, or you do not defend that hard, or you are taking shots that you normally wouldn't take etc etc.
Taking it seriously means you do all of that, not taking it seriously doesn't mean you are missing balls or giving bad pass or just losing ball control, those are not just not taking it seriously, those are stuff that a team in disarray would do.
It's obvious that they are not confident in their own abilities anymore, and they look like they are going to end up with being something terrible, it will definitely not be something easy. I get that it may take some time and I agree that Chelsea will be terrible for a while longer, but if they hire some people who will take care of the team and the squad properly, they may build something better for the future.
I still think that their transfer window moves are great, they are getting young stars for a lot of money and put it on instalments and sign them for long terms, allowing them to either play those players, or just sell them later for more money, or just quick cash. That could still make things good, and I believe that we are going to end up with something that may not do that well, it could take some stuff that will not be all that easy to handle, so that's a tough thing.
