He could retire or have a final season in Europe or MLS. Playing for Al Nassr in the SPL provided Cristiano Ronaldo with earnings which other players only dream about. If he played in the MLS he would add more fans in a new league that will host the world cup next year.
What is he going back to do in Europe, players that are just 34 are being pushed outside Europe, what is a 40 years old man coming to do in Europe. I know Ronaldo might be quality and Goated but can we be honest to ourselves, that he will become the most non existing player on the pitch if he returns, age is always a factor when it comes to sports.
Ronaldo should retire at Saudi, going to Lisbon shouldn't be with the intention of winning title for the club but rather to pay respect for starting his career.
