The new management is ambitious and bold with their decisions. I like it. Now let's see if they have the ability to back this up.
Keeping players not needed out of the squad can be both negative and positive. The positive side is that you create a team focus on committing to work early, without distraction or awkward moments. That is very important when you have a new coach, new ideas. Another is that you send a clear message to some that they are not needed and would go to the stand if they refused to leave. Until now players like Chiesa may think he is too important, at least on the financial side, that the club must renew on his term, or play him even without renewing. Well after this, he may rethink his position.
The negative for sure is devalue their price. But in the market, you never know. If more than one club has an interest in a player, there will be competition and a fear factor that can make the sale easier. Giuntoli has a very difficult task, but not impossible. He seems confident as well, let's see what he is made of.
The next few weeks will be very interesting.
