In my book, it's wise to ride out the season and assess a coach's performance afterward. Yet, Bayern Munich's honchos must've had their reasons, and we gotta tip our hats to that. But don't forget, football isn't solely about hoisting trophies; the odyssey and education are crucial too. So, even if Bayern falls short of the treble this time around, they can absorb the lessons and bounce back with a vengeance next season.
We only see the team playing on the field, but we don't know what's going on in the dressing rooms and what kind of relationship the coach has with the club owners. Such decisions are not made just like that, apparently it was a forced decision if it was taken at such a crucial time as now.
I don't believe that becouse of Bayern being one point behind Dortmund in the table could have made the decision to sack Negelsmann, that sounds too dubious to be true. I think that the reasons for this decision are completely different and they will not be announced to us. Something for the public will be said, but no more.
