There is no way Ronaldo will consider returning to Manchester United after his previous experience that led to him moving to Saudi Arabia. I also think he will rather accept a move to Sporting than return to United, and with the way things are playing out I think he might even retire at Al Nassr.
What if returns as a coach or sporting director, what will you say?By the way, he loved Manchester United so much that he risked his reputation with the club by going on air and criticizing on how Manchester United is being mismanaged and why things have to change. So who knows? You could see Cristiano Ronaldo in the Manchester United dugout one day.
In addition, if Ronaldo becomes a sports director or even a coach at Manchester United, I think that could happen if Ronaldo decides to pursue a career as a coach. But we all don't know what Ronaldo will do after he retires. It could be that he is not interested in becoming a coach and prefers to enjoy his success. Because until now I personally have not found any news that says that Ronaldo will become a coach after retiring. Besides, in my personal opinion, what Manchester United needs right now is not Ronaldo, but the point is they have to be able to rearrange everything from the beginning well. Because basically Manchester United's problem lies in the management team and all its ranks right now.
