Seems like a strange signing for them considering they could get almost anyone.
PSG seems strange to me, full stop. I get the distinct impression that with the French tax structure being what it is, they refuse to spend the ridiculous mountain of cash it would take to be a legitimate CL contender, but want to spend enough to collect players that contribute to their brand, can easily dominate domestically, and make it look like they're trying to win the CL. It always seems to be a show.
Probably the club I dislike most on the continent though, so maybe I just see what I want. Whole club just seems wholly fake.
