Ronaldo may not be able to play CL at all in the coming years. Let's start with the problem about his salary. Would he have seen the light this season and maybe just accept that a lower salary is also acceptable? He is no longer the Ronaldo he used to be. In the CL he has almost all records to his name. PSG have an extremely difficult route to the title with Bayern Munich as an obstacle. Then you could also draw Manchester City the following round if you are unlucky. But I think the draw has not been drawn yet and will be drawn every round from now on? Manchester City has no problems with RB Leipzig.
Ronaldo itself already rejected by many teams that were always being qualified for the champion league. He has no chance to play at CL once he didn't get a team that will be qualified for Champion league for next season.
The hardest thing to find a club that wanna pay his huge salary every year. There would be another problem once ronaldo was making a problem in the club itself adn that's gonna affecting the performance from the club.
City is far greater compared with leipzig but it's too early to talking about the reuslt without trying to see the match. The match will come next year and we have not yet passed this year.
