It is true that Ronaldo as maintained his place as one of the greatest player in football history, but his present in Chelsea current squad is not needed because already , age as affected his form in his former clubs.As such his playing style is quite archaic. Chelsea as been a club that attains victory through team work play, Ronaldo will not be considered fit for the team.
Chelsea never try to confirm if it was interested with ronaldo. There are only so many rumous but these are just rumours. I will not consider rumour as a thing that's gonna be real as long as there are no relable sources who have been confirming it.
Ronaldo itself is still too far to become a candidate as new player for chelsea.
It's not just now that we hear rumors about Cristiano Ronaldo with Chelsea. Last summer's transfer market he was much talked about going to join Chelsea. However, the Chelsea coach, who at that time was still Thomas Tuchel, confirmed that he was not at all interested in Cristiano Ronaldo. And it was Manchester City who were closer to Cristiano Ronaldo, but when they were one step away from reaching an agreement, Manchester United came and managed to persuade Ronaldo to return to Old Trafford.
The same thing is happening right now. Potter has confirmed he never interested with CR7. I think that so many rumours were just appearing to create the hype. These rumours could come from any parties and we shall wait from the official announcement by ronaldo. Ronaldo itself was in a very bad situation caused by he was going back with portugal after losing from morocco. Ronaldo is in a very bad mood for now. I guess he will be making some confirmation later.
There are bunch of speculations about what's gonna be next team for him.
