I also think the same thing with PSG's management, 80 million is a high price for a Skriniar, PSG only accepted Skriniar's transfer with 50 million + 1 player and Inter Milan has rejected this offer.
FYI, apart from PSG, it turns out that Chelsea are also interested in signing Skriniar, from the news I've heard, until now, negotiations between them are still ongoing.
What do you think? Has Inter Milan made a mistake by refusing an offer from PSG?
I don't think so, Skriniar is really a good player for defense of Inter Milan and it wouldn't be so easy to substitute him, that's why Inter Milan refuses offer for him. I see Koulibaly as a good substitute for Skriniar, but I don't
think so that Napoli and also him will accept to transfer to Inter Milan.
