We were surely not expecting to see Marseille beating all the teams in the French league and losing the game against Strasbourg was not surprising for us. However, I didn't watch the game but when I was checking the game stats for the match between Strasbourg and Marseille I saw Marseille had much better chances and many more goal opportunities in this game which made me think Marseille could even beat Strasbourg.
Regardless of their match against Strasbourg, I think Marseille still has a good chance to race with teams like PSG on the top side of the table.
Strasbourg are a strong team when playing at home so I am not really surprised by their win over Marseille.
Overall Marseille played better in this match but they were unable to score because Strasbourg played more effectively.
Regardless of this result Marseille are a strong team in Ligue one this season and they still have a big chance to compete at the top of the standings this season, this is their first defeat this season so we can't overestimate it either.
To be fair while Strasbourg could be strong, Marseille is much more strong and this is why everyone assumed that they would win. I am not saying they were a bad team, they are good at home, and this resulted with a win obviously as we can see.
However, Marseille spent so much money and did so well until this game so everyone assumed maybe there was a chance Marseille could win with ease, or even if they would have hard time, get a win barely. None happened, Strasbourg ended up getting the win which is shocking to me but I hope things get better with time and Marseille could close the gap once again, losing these unexpected games hurt their chances to be second. Nobody other then PSG will be first of course, I always think like that, even without Mbappe.
