Mission signing Marquinhos
Step 1: Pay Benzema 150 000 € (exact price) to find/get hold of/make a sex tape with chairman Nasser Al-Khelaifi s***** the balls of Zlatan and/or Laurent Blanc and/or Valbuena.
Step 2: Give Mr. Aurier a call. Make him announce another periscope-session at July 2nd.
Step 3: Give Mr. Nasser a call and explain that if Marquinhos is not a Barcelona-player by July 1st Aurier would have evidence to back up his claims in the next periscope.
Step 4: Let Aurier praise Nasser and PSG the day after Marquinhos has joined Barca.
Alternative plan
Wait until the world runs on renewable energy and Qatar is broke, then they have to sell.
Note: Might backfire as Qatar funds most of Barca as well.
That is genuinely the only two realistic ways of getting Marquinhos
