Cristiano Ronaldo will "probably" play out the final years of his career in MLS, according to his former Manchester United and Portugal team-mate Nani.

Five-time Ballon d'Or winner Ronaldo has established himself as one of the sport's all-time greats, winning four of his five Champions League trophies during a nine-year spell with Real Madrid.

He left the Santiago Bernabeu as their all-time leading goalscorer and has surpassed 700 for club and country since moving to Juventus in 2018.

Although he is showing few signs of decline – as evidenced by his 21 goals in Serie A this term, equal to his tally in 2019-20 despite playing nine fewer matches – Ronaldo is now 35 years old.

Retirement does not appear to be imminent, however, with his Juve contract running for another two years, and he is seemingly planning on a spell in the United States before calling it a day.

"A couple of years ago, he told me that he will probably end up in America," Nani, who plays in MLS with Orlando City, told ESPN.

"It's not 100 per cent, but probably. There is a chance."

Nani is convinced by the quality of football in MLS, even if he does recognise there is still plenty of room for improvement.

"It is a great league," Nani said. "Obviously there are points where we must improve as a league, even in the quality of the players.

"[But] here you have fantastic clubs, well organised with fantastic conditions, great coaches, great players. You see every season improving.

"I think we all have the conditions in this league. We are in a great country, everything is around us. It is all about being better, not being afraid to improve."
