There is no statement from Ronaldo that he is interested to return to EPL. I doubt if Ronaldo wants to join again Man United and plays in EPL again. I think he feels happy in Al Nassr although he doesn't win SPL trophy. Anyway, it is untrue if you assume he has no pressure. He is expected to win Saudi league, it will be always a big pressure for him as long as he doesn't win SPL trophy. I don't want to compare his condition when he played under Ten Hag's management and when he plays in Al Nassr. Surely there are too many differences, he has no much time to play when he is managed by Ten Hag. This coach and his coaching team never showed a respect to Ronaldo.
He will not return to Manchester United, and boss of the club does not welcome him back, I am quite sure about that. Moreover, Cristiano Ronaldo is enjoying his life with lot of money in Saudi Arabia and with very little years left in his career, he will not return to a club in crisis like Manchester United. He was treated badly once and will not want to be treated the same way again for a second time. His high ego will not let him accepting such treatment from Manchester United boss.
I strongly believe that Cristiano Ronaldo will continue his career in Saudi Professional League, money is important, and he does not lose his chance to play for his national team. It's enough for Ronaldo.
