PSG 1 -0 Rennes
Luis Enrique is more worried about the Champions League match at the moment. PSG will play against the powerful Arsenal in the next Champions League match. Arsenal team is strong, also the match is Arsenal's home match. So it is challenging to perform well in this Champions League match against PSG. Even so, Luis Enrique will do his best to beat Arsenal.
Defeating Rennes 3:1 at home I think was a good preparatory performance for Paris Saint Germaine who'll travel to London in the midweek to face English Premier League club Arsenal in the UEFA Champions League competition. Like you rightly said, Arsenal is a very strong team that's very capable of beating any of the top teams in Europe but I believe that Luis Enrique has all it takes to fight them.
Paris Saint Germaine have dominated the French league for far too long and must extend their dominance to Europe now before they can be considered as an European heavyweight. A win for the French champions at the Emirates will help improve the mentality and confidence of PSG but I strongly doubt they'll be able to beat Mikel Arteta's men.
