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.
After the first match and the results that the ideas of Ten Hag brought, I think Ronaldo will even agree to go to Sporting
In the end, this is not the worst option as he will get a chance to play in his beloved Champions League and most importantly avoid the risks of continued embarrassment by United. In the Premier League, I support United but I have a big feeling that this season will be completely lost.
