Very likely.
ETH told him what he'd expect from his #9 for example pressing and if Ronaldo can't do that he's sorry but Ronaldo won't start. So Ronaldo threw his toys and told Mendes to find him a new club thinking he's still hot shite. Turned out he's no longer hot, only shite. This explain why he wanted out so late despite it's clear that we won't have CL football this season months ago.
ETH of course won't tell the press that he doesn't want Ronaldo as his #9. If so the media and Ronaldo's fans will blame him. Imagine all the drama and the pressure to perform of he did so. Any draw or lost the subject "if you have kept Ronaldo blah blah" would be brought up again. He keeps saying he wants Ronaldo and Ronaldo is in his plan to avoid that. He doesn't lie he only does not tell the whole truth. He has a plan for Ronaldo only not as his starting #9.
United of course don't want to be blamed either so they just play along. They also want a fee as well that's why they keep saying they want Ronaldo to stay.
Of course all the above is only my opinion but it does explain everything I think.
That accords 100% with my own opinion, so you’re in excellent company
In addition, I think the club have every right to expect some sort of financial compensation for releasing him and Mendes from their contract. Fans have (rightly) complained about player power being allowed to fester and grow throughout the Ed Woodward years, yet when the club suddenly take a hard line and remind a player some fans don’t like of his contractual obligations, those fans start screaming “just let him go”. Like that sends out the right message to players and, even more so, their agents…
So either United get a fee and Mendes accepts a much reduced commission, or Ronaldo stays. He’s had much of the wind taken out of his sails by top clubs not lining up for him; with any luck he’ll knuckle down, accept his role as a rotation and bench option (which will still see him getting plenty of game time) or, if he’s an arse, get sidelined and shipped out in January.
