If I see the last match, Marseille only focuses on Ligue 1. but it's not a problem if it's a chance to better because PSG is a great rival that needs full power and energy to concentrate. So far they create the same points and progress, the statistic has been better with 5 wins in a row, maybe because their players are pretty good on average which makes Alexi Sanches look comfortable with the strategy.
Marseille was not focus to France league only and their poor performance on champion league proven their current squad is not ready to playing for tight schedules from several competitions and i have to say Marseille in champion league is only mediocre team even on season 2020 they was stopped at group stage with only once win from 6 matches and France league is different because they know their opponents in this league so no wonder if Marseille has better performance in France league and althoigh i am doubt but i hoping they can be more consistent and provide decent challenge to PSG for race title
