From the latest info I got that Manchester United are ready to let Ronaldo go and let Ronaldo go if there is a team that wants to sign him but unfortunately, from the latest info I got also all the big teams don't want to sign Ronaldo and maybe there are only one or two it's Dortmund even if it's just a rumor and also Sporting. There is still time for Ronaldo to leave but no club really wants him and apart from that, after seeing his first match with Ronaldo and Varane on the bench I think Erik ten Hag made a big mistake in their first match.
I haven’t heard that Manchester United is ready to let Ronaldo leave if there is any team is willing to sign him and have him on its squad. In my opinion, It has been obvious that Ronaldo is tired of staying with Manchester United and wants to leave. But there isn’t any top club that is willing to have him. That has been obvious for a while. I don’t know why Manchester United would opt to let Ronaldo leave now though.
I don’t know how Ronaldo would fare if he ever decided to leave Manchester United and go to Dortmund. I also wonder if Dortmund could afford to have him.
