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.
Rumor, there is no certainty in it. After Ronaldo officially parted ways with Manchester United, no one has made an official bid on Ronaldo. The news circulating in print and electronic media is just a figment of the imagination, journalists continue to fry news about Ronaldo to attract reading interest from published news.
Ronaldo who still has big ambitions to appear in the Champions League, will choose a club that can make his dream come true. Chelsea is a good club and is still active in the Champions League, but with the current conditions it is very difficult for Chelsea to win the Champions League.
