Borussia Dortmund has been doing this for years. They get the biggest criticism for this, but nothing changes. They see it as a business and think that selling players is more important than winning the championship. The criticism of football fans about Borussia Dortmund doesn't change the situation. They always sell their best players and try to find and train other players. They are actually very good at it.
Maybe this understanding will change and they will try to win the championship until the end and maintain their quality squad, but some clubs can't give up their habits easily.
The criticism that comes to them does not change them, yes they do not care about it because they continue to try to do business from the sales of players that they do. For a big team like them, actually listening to criticism from outside is also necessary, because some of them are also criticisms that can build them to be better, but unfortunately they do not do that.
Business in football cannot be separated, but they must realize that they also need achievements. They cannot be selfish as a team, they also have to see how thirsty their supporters are for a title. That is actually very possible for them to achieve as long as they are serious about pursuing it.
