Carlo still has to manage the players he has at his disposal. There seems to be a view held that another manager would be able to get long term higher levels of performance out of these limited players maybe due to some sort of rock solid tactical set up whereas Carlo has an old fashioned brand of man management and pragmatism that only works in a short term on top players.
I don’t see this. We’ve tried the other approach, Koeman, Silva, they have a single way of playing and you get a short term burst from some players but then performances nosedive. The league works out the tactics and then when performances go south the managers have no answer. See Arteta currently. The players stop playing for them and they get fired. Rinse and repeat.
Good man management and pragmatism might be exactly what’s needed for this squad. Keep some of these clowns onside for long enough until they can be shipped out.
It is impossible to answer.
I'm pretty sure Ancelotti is excellent at handling players and he knows football (no Sacchi students are incompetent in this area). But football is constantly evolving. It is not enough to be a good manager, but you must have the best possible people around you. There are so many factors you need to consider. Physiology, data analysis, psychology, etc.
The game is also evolving, and the last decade has been characterized by more sprints, and more running. So the players must be in top physical shape to withstand the intensity, and to avoid injuries. Here you must be up to date with the latest in science.
One must have passion, and constantly seek to improve oneself. Sacchi (Sacchi is a good friend of Ancelotti) touched on this topic when Ancelotti was fired in Bayern, and suggested that Ancelotti did not have the same passion as before.
To sum up, I have no doubt that Ancelotti is a good coach, but I doubt more whether he himself has developed, has the same passion, and whether he has the best possible people around him. If we are to take the next steps, we must be innovative, and take advantage of all the small factors that can benefit us.
