Chelsea has shown interest in signing Cristiano Ronaldo specifically for the Club World Cup 2025. This interest is said to depend on Ronaldo's performance and how well he adapts to the team's style during the tournament. No formal offers or approaches have been reported at this stage. The transfer is conditional on Ronaldo's contractual situation with Al-Nassr, and negotiations might advance if he becomes a free agent. According to Tuttosport, both Manchester City and Chelsea are considering acquiring him. Despite being 40 years old, Ronaldo continues to be a top scorer and a key player for Al-Nassr, which makes him an appealing option for European clubs. The potential signing is not necessarily an indication of his stay for the 2025-26 season, as the focus is primarily on the Club World Cup.
