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.
Yeah, after having good results in Premier League Newcastle United is also looking for few quality players those can help them for improving things as they could be able to have place into next season's Champions League and Cristiano Ronaldo is surely can take part into their success even nothing is clear because right now we have another option for the Newcastle United with Harry Kane is also in rumours but for better things we have to wait for the real time news.
Cristiano Ronaldo is surely losing his options and now have to wait for the next move which will help him if he wants to stay in Europe or going to any other country for his rest of career, which is now having not good indications after exit from Manchester United in bad situation.
