Why did Beijing Guoan suddenly fire Setien?

, I don't understand why he wanted to hide his strength in this game. In fact, not only the club's senior management did not understand Setien's platoon, but even his own assistant team had put forward many opinions, but Setien did not adopt them. This shows how arrogant Setien is.

If the arrogant Setien continues to coach, the club management is worried that he will bring Beijing Guoan to an out of control. He is arrogant and does not know how to humbly accept external suggestions. He only knows to do his own thing and do his own things. At that time, there will probably be big problems in the FA Cup final. Therefore, firing him in advance now will help Beijing Guoan unite and prepare for the final FA Cup final. And this may be the real reason why Beijing Guoan decided to dismiss Setien.
