I really don't understand Marseille. They had a huge chance for winning a title in this season. But they just turned down the big opportunity after being eliminated by a small team. After eliminating PSG I was just seeing Marseille as the champions already. Because they were very strong among the teams remaining in the cup. But they gave it away and now they can just fight for the second spot in the Ligue 1. Because they let their championship chance slip here as well.
Their performance against PSG here was horrible as you remember. About the Rennes match I can only say that it will be really difficult. Rennes can take advantage of their demoralized condition and even beat them. I could pick Rennes' double chance for betting.
