Who leaked the news of Julian Nagelsmann's Bayern Munich sacking?

While it was certainly a decision made by Bayern Munich's top brass, it wasn't exactly their intention to have their choice to axe Julian Nagelsmann leaked to the press before they were able to speak with the manager directly. Over the weekend, sporting director Hasan Salihamidzic explained part of the timeline of how Nagelsmann found out he was going to be sacked and ultimately replaced by Tuchel on Sport1's Dopplepass. Much like Nagelsmann's recent tactics sheets ahead of Bayern's 2-1 loss to Bayer Leverkusen in the Bundesliga, someone leaked the explosive news of Nagelsmann's imminent sacking to the press that the club. Apparently Brazzo did not mean to suggest it was Tuchel or his agent.
