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.
