I am not sure if this is a "healthy" move by him. PSG is a mess, too many alpha people within the club, no continuity. He is 22 years, taking his first big move and going straightaway to a club which is forcing to buy everyone in order to win the CL. It will be interesting to see how it works out for him at PSG.
It looks like PSG paid a similar amount we paid Atlanta for Hojlund. Difficult decision which one to prefer but at least they are put on the very same level. At the moment, Ramos is the better player with his skills and continuity, however, Hojlund is a gem, just starting to explode, and under ETH he will rise.
