This saga is hilarious. If Barca and Bayern start a money war for this clown they're complete idiots. Rabiot is in the worst possible spot right now. After he destroyed his future with France NT, he did the exact same thing with his club PSG. He won't sign new deal with PSG, the club does no longer trust that traitor.
So what does Rabiot have ? 6 months without playing and he lost his best negotiating argument which was "PSG offers me 8-10m so you gotta do better if you want me" cause PSG doesn't offer him shit anymore. He's the one under pressure cause he needs to find a club ASAP.
Why would Barça or Bayern offer him 10m if they're not dumb ? I mean there's 0 competition for him. Because in this whole world there are only 5-6 clubs that are on Mr. Rabiot's level: Barça, Bayern, Juve, Real, City and maybe Liverpool. Real, City and Liverpool don't seem to give a shit about him. Juve is too busy buying Ramsey. So basically there are only 2 clubs left for that idiot. They should know that and offer him 5-7m wage at most.
That little fucker is trying to create a bidding war as you can see but he put himself in a shitty situation. He tries to fool everybody as usual. If Barça and Bayern are just slightly smart they'll understand it and act accordingly.
