You are right YuginKadoya, it is no secret that Stuttgart is facing a lot of problems at the moment.
If the new coach attempts to fix those problems quickly, it will be very difficult for him. It is imperative that the new coach is given time to adjust to the newly implemented system.
In all honesty, I am very skeptical about Stuttgart's ability to improve in the near future.
My opinion is that it will be really difficult for them to overcome the difficulties that they are facing at the moment in order to get back on track.
It is my hope that when they bring in this coach for a long-term contract, they know what they are doing.
And probably change some players that are slacking, in some teams there will surely be a player who likes that it is not always that the fault was only on the coach and it is not the solution to always change the coach, and it is not likely to mean that the solution is on the coaches alone, they need to check possible players change or trades, for necessary change in their progress I think this is needed and not to change the coach alone,
In some cases, coaches believe that they should give the players enough time to adjust to the team and get to know each other. And oftentimes, especially with smaller clubs, it tends to backfire. In some cases, it is not in the nature of that player to play with a certain tactic in that situation. And it is better to change the player. If you change the coach at that time, it is going to be bad because the whole team will have to get used to the play style of the new coach.
That is obviously not optimal for a team in my opinion. I think the most appropriate solution for a player who is not playing very well is to loan him. But it is better to sell that player because smaller teams are always more likely to be interested in a player who can be bought cheaply. It will probably have a severe impact on the career of that player, but as a coach you Gotta do what you Gotta do
