CR7 could play in theEuropa League, which is not for him
When Ronaldo signed his contract he knew he was committing to working with players that were not to his level or won a trophy since 2017.
Manchester United coming in 6th place this season means that they would play in the Europa League something Ronaldo definitely does not want.
If Ronaldo was to stay with Manchester United he would not be able to participate in the competition that he loves so much.
A competition that has seen Ronaldo win five trophies and be the all-time record goalscorer with an outstanding 141 goals in 183 appearances which is a 78% goal scoring rate. Ronaldo only played in the Europa League once which was then the Uefa Cup once. During the 2002-03 season he played against Serbian outfit Partizan in the first round.
