Ronaldo is already a multi millionaire, & whilst money will be important, it won't be as important as finishing a glittering career on a high a note as possible.
A solution would be for Ronaldo to accept £15m a year on a 2 year deal. City pay Juve £10m & give em a lifetime supply of barmcakes, & also point out that they'll save £20m in the process. It's a win/win scenario all round & one I could easily live with.
City get Ronaldo, his goals & commercial circus for a combined £20m per season over the next two years whilst we see how well Torres, Delap & Jesus progress. It also leaves our powder dry for Haaland next summer. Sorted! :-)
