That's easy. The review will determine their deal to be at fair value. They are no long-term threat.
The interest of a global deal to a potential sponsor would be that they pay lower for a global deal than they would for multiple deals in individual markets, so I don't see these new rules as a threat to our share of CFG sponsorship deals. Don't forget, the rules don't ban associated deals, they just say they will be assessed at fair value.
Also, the PL has no jurisdiction over the CFG, so they would be told to get stuffed in any request for sensitive commercial information and if they pushed it, they would lose.
Lastly, the new rules say the PL can take into account FMV assessments provided by the club. It would be very brave, and stupid, of them to come up with a different number for our share of a global deal if ours was truly independent, especially as they have listed all the elements to be taken into account in FMV, so we can completely mirror their approach.
