Young strikers who have played in the EPL will certainly not have much difficulty adapting to a new team in Ligue1, especially since the competition in Ligue1 itself is not that competitive. However, with Greenwood's presence in Marseille in Ligue1, it is certainly hoped that it can bring a little change to the competitive scene so that Marseille can become a tough rival for PSG next season, although I am also not immediately convinced that Marseille will be able to stop PSG from winning again in Ligue1 next season.
Becoming a tough rival for PSG isn't something that can be made possible by a single transfer deal don by Marseille, looking at the ligue 1 PSG has got the best depth such that it will cost others a fortune to get such depth PSG and then it's been a normal over a long time for PSG to always have their way around the ligue 1 but then this doesn't dispute the fact that PSG can at some point loose dominance in their domestic league but it wouldn't be because a team got a single new player as there are good likens to such player in PSG. Marseille needs more to stop PSG. I know greenwood will help Marseille a whole lot and will definitely not find it difficult as he has played in a more competitive league.
