PSG already got what they needed to have. In the last season, they had superstar players but they didn't have a coach like Enrique in this team to help players have better teamwork and they have it. Also, Enrique is experienced enough to make PSgeven win the Champions League title.
But other than this, they have to give Enrique some more time and provide him the players he needs, Mbappe leaving PSG was harmful for them.
It will take more time before witnessing the progressive structure of PSG. Remember, they sold one of the promising player to Real Madrid and his space is vacant, no replacement yet for Kylian Mbappe. This is probably the picture where Paris Saint-Germain headcoach, Enrique steps in, he will deliver excellent job during his prime in Parc des Princes stadium. He just need more time to settled down and arrange for the very best. Luis Enrique will do the necessary changes to boost the performance of the club.
