Ronaldo is a brand name and he wants to preserve it. He wants to leave so this is to say that Ten Haag doesn't like him that's why he doesn't get picked. He's saying United is the failure, not himself and he's got a good argument there. The hype around it is perfect, United is a circus and he's pointing out why. At this point, he can say he was top scorer last season so he should be a starter. United will look terrible no whatever what they do, even signing him in the first place.
The hard fact is that United are shit, won't make CL, and finish trophy less. All the commentators are full of pride for United and trying to justify United's numerous fails but can't handle the fact that clubs like Arsenal and Spurs are far better.
Love him or hate him, his PR team are smart and he leaves United who are destined to fail. Owners, management, and players take the blame as Ronaldo wasn't picked. Its a really good exit strategy. All he has to do is score a few goals for Portugal and he's that's his justification.
