PSG still seemed determined to win and they did that when they visited Nice's headquarters by securing an additional 3 points from that match. Even though they are playing without Mbappe, this is not a problem for PSG and they have to start getting used to this so they don't become dependent on the French star.
Apart from that, Nice, which I initially favored to win, failed to add to their points collection, but at least their position to play in the European league is locked considering that Lens only has one game left so Nice's points will not be overtaken.
Against Nice in yesterday match was certainly one of the experiments for Luis Enrique by fielding their reserve squad, for now I think Luis Enrique is no longer targeting victory in each of their remaining games because there is no longer a target to get points, so that is what makes Enrique field their reserve squad in that match, If PSG still need points then it would be impossible for Enrique to field their reserve squad against Nice and that can be seen from PSG previous matches which are even very rare PSG to field second-tier players even though they faced weak teams before they won the championship trophy this season.
About winning the game, of course, it seems that it is beyond what Enrique expected, because indeed every reserve player will of course try to show their best performance when the coach gives the opportunity to play, because then it will make their chances to return play in the next match will be open, now Nice dream of playing in the Champions League has disappeared after an inconsistent season journey, But at least they are still lucky enough to get a place in the Europa League next season.
