Rumors about Ronaldo never ended, before were Chelsea and now Atletico Madrid? I don't think he will accept this offer because he was a Madrid player before
You can imagine how Madrid fans will hate it if it really happened, It's the same when last season he was rumored to move to Manchester City until finally Man United became the last choice.
I bet Ronaldo won't move both to Chelsea or Atletico Madrid. He won't ruin his reputation by joining the rivals. It is only a rumor, there is no official announcement that Atletico Madrid makes an offer to sign Ronaldo.
This seems to have passed because now the news that Ronaldo will move to this team is no longer new and only focuses on issues.
But if you look at last season's move from Juventus to Manchester United this will be something interesting considering that at that time there was also no really hot news other than in the last few days rumors about a move to City but a few days later it was immediately officially announced by MU.
It is possible that there will be surprises like this again now.
