We still remember these words how he said that and Ronaldo still has the ambition to play in the Champions League even though he is old and not fit anymore, but what we see seems to be that it will be difficult for European teams to accept him back, starting from high salaries and failing in the World Cup with his poor performance and now he is not aggressive anymore a little weak to be on the field so I think it is difficult to determine he will play in the UCL.
If European clubs are unable to sign him, then another option is Al-Nassr, who is ready with a high salary in one season and sponsors are ready to wait for Ronaldo.
Yup, poor performance during World Cup will make it even more difficult for Ronaldo to get a club in Europe. So far, there are no more rumors reporting European club interest in Ronaldo.
Because he doesn't have a club, Ronaldo is currently reported to have chosen to train in Madrid. He is very lucky that even though he is no longer a Madrid player, he can still train at his former club.
Maybe, if AC Milan were still held by the duo Berlusconi and Galliani, Ronaldo would be the player they brought in. Somehow, this duo very often able to bring in old star players (Ronaldo (brazil), Ronaldinho, Robinho, Ibra, Torres) and what's unique is that they manage to bring in these players for a lower salary.
