It doesn't feel like Ronaldo will be able to find a team for himself which is already in the Champions League now. Because there is no such team having serious interest in signing him these days. There is still time for even the start of the transfer window of course but I'm not very hopeful about that. The only team I've heard of in Europe is Newcastle for now. If Ronaldo is ready to be patient he should sign a deal with them. They are already doing great in the EPL and they have a potential for the CL.
Otherwise Ronaldo seems really likely to go outside Europe, especially that Saudi Arabia team Al-Nassr.
everything is just rumors there is no definite certainty which team is really serious about signing Ronaldo in the January window. newcastle united which has quite good finances and its performance in the domestic league is also good so that the media associates it with ronaldo in the transfer market. Ronaldo does have a great desire to be able to play in the champions league in his new team, so that will be the main point he will rely on in the future. On the chelsea side they are looking for a sticker with more experience this season but the arrival of Aubameyang was not a big impact but not a bad performance but he needs time to make a big contribution. whether chelsea signing ronaldo in the january window is worth the wait.
