It's honestly not a bad signing, and either 20m now and non-cup tied or free agent in the summer are both decent deals. I think some might be a bit disappointed because they rather want XYZ for that position and feel like the singing of Özil would replace those, but otherwise it's definitely not a shitty signing and way above Di Maria for 3x the money to bail PSG out of their FFP debts. A creative player that is already proven in Spain and would be an immediate boost to the current midfield. In theory he should link up very well with Messi.
