Cristiano Ronaldo hasn't better performance in World Cup with 1 goal scored trough penalty kick from 4 matches with Portugal at World Cup 2022 I don't think any Champion League team participants want to signing him, although have been free agent I don't think easy for Cristiano Ronaldo get contract with team still in 16 round of Champion League. He has underperformance at World Cup and difficult give more contribution for his national team not only less scoring goals but also he has bad statistic with Portugal without any assists created.

Still possibility and easy for Cristiano Ronaldo reach contract with team participant in Europe League but he needs cut off salary more than 30% until 50%, difficult for any team want to pay him based on salary received with Manchester United except he has join with Saudi Arabia team.
