Mason Greenwood is actually a good player, it's just that he was involved in a scandal that made his career not run smoothly and he took a lot of rest before he started being loaned to other clubs, previously he was loaned to La Liga club Getafe for one season and he created 6 goals and 6 assists in all matches, unfortunately this club could not make it permanent because maybe they couldn't afford to buy Mason Greenwood from Man United but Marseille was willing to buy him and give him a place as a main player, currently he has scored 3 goals from the 2 matches he has played, I think he can compete in the top scorer race if he continues to score goals in every match.

He got a lifeline when key witnesses decided not to cooperate with investigators and the case was dropped by the Crown Prosecution Service (CPS). Against all odds like protests from Marseille fans Roberto De Zerbi believed in the English striker. The Italians vowed to defend Greenwood as a son and looks like the Italian coach made the right decision. Three goals from two games is a historic performance by a Marseille player and if he continues this way, he will celebrated in Ligue One.
Usually, players who are involved in scandals will find it difficult to continue their careers because they will receive a lot of criticism from the club they will defend and they have to turn a deaf ear to it in order to continue their football career because they are only 22 years old so it would be a shame if their careers were ruined while they have the talent to show their abilities.
The interim results are quite good, I hope he can continue like that so that people's hatred of him turns into praise, he might be able to become a new star in League 1 replacing Mbappe if he can continue to score goals in every match.
