It as if when it comes to bringing in coach Chelsea don't plan well to know if the coach is capable of doing job, they just do try your luck I'm every coach they pick. I don't blame Todd Boehly for sacking is coach's because these coach's are not making any good improvements, so I don't think their is any need of keeping coach's that is not transforming the performance. If Chelsea is trying to go for young players, it should be players that are talented with good experience, not just players that can't won't be able to make any effort. Chelsea needs to plan well, no good improvement for a very longtime.
I think the Chelsea owner should be patient with the managers, if he believes that developing the players is simple, why can't he choose to train the players himself? Chelsea has the Premier League youngest squad and wants to win every trophy. If I am not wrong, I don't believe Chelsea has any players above the age of 30 in their current squad, they are only signing young players, and the management expects them to win trophies. In my opinion, this is why Manchester United did not fire Ten Hag, they are afraid of having a bad season like Chelsea.
However, despite how badly Manchester United performed last season but did not fire their coach, management is still pushing to offer Ten Hag a long term contract because they believe he will bring good outcomes to the club. Chelsea management must be patient with their managers, if you believe that the coaches they fired did not produce positive results for the club, I disagree because we saw how Pochettino turned things around at the end of last season, but Todd Boehly believes he is not capable of managing the club.
