Greenwood is only 22 years old. He has had such a good start that I am sure Manchester United regretted letting him go. He was good in Spain last year, he looks good in France this year. He may return to England soon. Mason Greenwood was also playing well in Manchester United but his career came to an end due to the problems he had. He continues to stand out with his individual talents.
What he did off the field made his career a bit stalled and eventually made some teams reluctant to bring him into the squad. In terms of ability he is one of the talented players, but in this case I can't blame anyone because they must also think and see the attitude or behavior of the player.
I think he is still lucky because in the end there is a team that recruited him and gave him playing minutes, namely Marseille. Some people might say to be professional and forget the mistakes he made, after all it was also off the field. But it won't be easy, as easy as saying that, everything must have a process and I think it is a social punishment.
