On the other hand, this deal will also see Mason Greenwood contracted for 5 years and I think Marseille made the right move. However, if progress shows good things and Mason Greenwood's performance can be sharper, then Marseille will also benefit from his sale in the future. But first Marseille's focus is on needing his services to improve the attack line which has started to dull since last season.
This is a good step from Marseille considering that the results they got last season were not good, only being ranked 8th in the Ligue 1 standings, even though the previous season they were in the top 3 of the standings. Mason Greenwood is also still young (22 years), this could be a double advantage for Marseille, on the one hand they get a new striker to add to the squad, especially on the front line, and on the other hand it's a long-term investment, last season with Getafe he was successful made 10 goals & 7 assists from 30 appearances, not bad at all.
