Last night Marseille played desperately against Panathinaikos in the Champions League qualifier and thus, it is likely that the condition of the Marseille squad was very drained in the match last night. Therefore, if Marseille is not quick to recover the stamina of its players, then it is possible that Marseille's performance in the next match against Metz in Ligue 1 may be slightly disturbed and or not optimal as well.
As for me, I don't think Marseille played poorly last night, but what I observed from the match is that Panathinaikos was just in good form yesterday, but Marseille played to their best, but the truth is that they were not able to score many goals with those good chances they had. And one thing again, sometimes playing teams from other leagues is hard because there are also great teams from other leagues. I believe Panathinaikos is a great team in their league and performed well last season, which was why they were called to play in the Europa League Qualification, so I expected them to gave Marseille a tougher time that yesterday.
But yes, of course these conditions cannot be an excuse for Marseille in the next match. Because yes, although Marseille will also play away, but considering that the opponent is Metz, the promotion team. So it is appropriate for Marseille to get full points again on the second matchday Ligue 1 later against Metz.
Yes, I am also expecting Marseille to be able to win their next match against Metz despite their playing an away game, but I know that it will not be easy to win Metz like that because before Metz was relegated, it always gave Marseille tough times to win them, but see how this time game will look like, maybe the strategy they use to win Marseille has changed, and even if Marseille wins Metz, I don't think it will be with many goals.
