Speaking of Nagelsmann, I much prefer him over Galtier, Nagelsmann is a young coach who carries modern football. it doesn't matter what the French public thinks, but what is certain is that he has the capacity as a potential coach. that is why, Nagelsmann was targeted by several big clubs.
So far, there is only information that PSG is in talks with Nagelsmann, and this could possibly be a profitable deal for both parties, since PSG with Nagelsmann can become significantly faster, which they lacked with Galtier. PSG have good financial resources, so I have no doubt that they will be able to make a good offer. But first, we should wait for official information, because so far it just looks like a rumor.
I heard that on the news when they said Nagelsmann is going to join PSG for the next season and they think the reason of their team failed in this season was because of the bad coach they had.
If Nagelsmann gets better results in PSG I think Bayern Munich will feel regret.
