I don't think that Ronaldo will go to Barcelona for next season, because Barcelona's condition itself is also in crisis so the best players like De Jong who are in Barcelona are also being sold to other teams by Barcelona now. But on the one hand Ronaldo actually also wants to be in a club that enters the Champions League next season to improve his career in old age because at the age of 38 after next season it will be very difficult to bring out his potential again in playing in any team.
And in this case I also agree more that Ronaldo wants to stay at Manchester United to help the team win the Europa League next season. But after that he will no longer be at his best because he is very old.
Barcelona don't have the money to buy Ronaldo, I just hope that it's rumour, Ronaldo should stay in Manchester United so as not to lose the respect he had earned, he has won it all as regarding all European titles except europa league, Messi stayed with Barca at their lowest point and only left when it was literally impossible to stay, I think Ronaldo should imitate such decision also.
Ronaldo has had great honor at Man United, when he decided to return to Old Trafford, Man United fans welcomed his arrival with joy. Of course that joy will disappear if Ronaldo really moves from Man United, the reason Ronaldo wants to move to another club is because he wants to get a share to play in the Champions League.
If Ronaldo moves to another club, it will certainly experience a big shock in the body of Man United, because a number of bad effects await the Red Devils if they lose Ronaldo in the near future.
Ronaldo's departure could disrupt Ten Hag plans to rebuild United's squad and leave a hole in the centre-forward position, as the stock of players who can fill the same position is very thin. Ronaldo is indeed known as one of the players who fills the wing position, but in his 30 matches with Man United in the Premier League last season, all of them played as a center forward, the results were very satisfying. He also managed to become the club top scorer in all competitions last season with a collection of 18 goals.
Manchester United could have chosen the option of shifting Jadon Sancho and Rashford to the center forward position, however, Sancho and Rashford number of goals was not as good as Ronaldo. Man United will try hard to keep Ronaldo because they do not want to face the competition next season without a pure striker.
