If Ronaldo moves to Chelsea following the trouble he has at Old Trafford and Todd closes the deal to get him, He might face more trouble at Stamford bridge because he is old to roll with the small set of young players at Chelsea which is similar to what he is facing at United. He needs a club like Bayern, Juventus or Napoli to fit in well. His era in the premier league is over because the nature of game has changed and the age bracket in the PL are way too younger than himself.
At least I believe Ronaldo needs a club that will give him priority in the starting eleven, because he needs something that will make a name for himself after ending his career in football, Manchester United did not support him to do that, and coach Erik ten Hag really destroyed his hopes that he want to end his career with some new achievements with Manchester United.
