Marseille coach De Zerbi believes Greenwood has a lot of potential for growth

The ex-Manchester United attacker scored two goals in the win against Brest last week.

De Zerbi said ahead of OM's clash with Reims, "He has to continue training like he is doing. Mason Greenwood is a serious boy, we are all satisfied with him as a player and as a person, for his behavior. He has enormous room for improvement.

"Against Brest we had a great match but we barely managed to hold the ball because the players were not available.

"He, like Luis Henrique or Elye Wahi, must not only think about attacking the depth but also make others play to weave the game."
