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.
Many people are waiting for official news, but remember that Ronaldo may not be out until next year.
If he is still asking for a big salary and selfishly it will be difficult to fit in with the change. As long as this unofficial news spreads. Ronaldo is a double-edged sword, he can help he can also harm. You have to know Manchester United let him go because he was out of control. If Ronaldo is still like this, they should think a lot because of his bad image towards Man United.
Big salary will make clubs not to be interested in him, but if he cuts that big salary down some clubs can be interested in him. It doesn't make any sense for Ronaldo to be collecting such an amount from a club and won't still be able to make the club win trophies. The big salary results to nothing.
