Rennes is in good momentum, before drawing against PSG, they managed to beat Milan in the Europa League play off. Even though in the end Rennes failed to advance to the last 16 due to difference the goal margin, the victory over Milan made Rennes gain confidence. Of course PSG will not be touched at the top of the standings, if PSG loses in the next 3 matches, it is not certain that the other Ligue 1 contestants will be able to overtake them. Such is the competitive level of Ligue 1 at the moment, with the depth of PSG squad, no club can break their dominance in the last few seasons.
The draw against Rennes was a bit disappointing, many bettors then thought that PSG chances in the Champions League were very low, because in Ligue 1 alone they had not been able to appear completely consistent. But personally, I don't think it has a big influence, Enrique will certainly try to win in the next match versus Monaco. The match against Monaco was an opportunity to gain better confidence, ahead of the second leg after that against Sociedad. I predict PSG will advance to the quarter finals.
PSG's loss or draw in the next match will not affect the competition for the Ligue 1 title, which is why this league is less competitive in competition because it is very difficult to break PSG's dominance as the strongest team in the league. The draw that PSG gets will definitely be linked to their performance in the Champions League because the actual competition there is full of challenges for PSG, because the competition in the Champions League will be much more difficult than in Ligue 1.
Winning by two goals when playing at home will make PSG have to be alert when they visit Real Sociedad's headquarters, because if they are careless, it is not impossible that Real Sociedad will turn things around. Even though I myself am more confident that PSG will qualify, Luis Enrique must try to do something so that this match will be easy for them to get a second win.
