PSG performances in the champions league against Newcastle United is unacceptable and Enrique is rightly feeling the heat. On the contrary, i think the manager is finding iot hard to build attacking or defensive rythm after signing lots of players at the start of the season. The coach definitely has to do better; with Bans coming up for few players including Muani; time is right for Enrique to proof himself.
You can see the line-up that Enrique used in the match against Newcastle. IMO, I suspect that Enrique is more speculative in experimenting with the system and rotating his players. In that match, Enrique applied a 4-2-3-1 pattern. Goncalo Ramos is the sole striker, Kolo Muani and Dembele play on the wings, while Mbappe plays behind Goncalo Ramos. We can say that during this match, Mbappe was rotated into an attacking midfielder or playmaker. maybe, IMO, Enrique wants to maximize his players' play. I mean here, Ramos, Kolo Muani, Dembele and Mbeppe were played as starting events. Unfortunately, the system he implemented failed miserably. Kolo Muani played poorly on the wing, which was eventually replaced by Barcola. Apart from that, Paris Saint-Germain's defensive line played disastrously. In the end, PSG fell, humiliated by Newcastle.
I think it was a wrong decision to implement a system like that, which in the end Enrique returned to implementing a 4-3-3 system against Rennes. but again their performance was not optimal, their stickers had difficulty scoring goals. Fortunately, Vitinha and Hakimi were able to score first to give them their advantage. Only after Kolo Muani came on did their striker score a goal to complete PSG's victory. Well, in the defeat against Newcastle, Enrique gained valuable experience because he was humiliated by Newcastle. In the second leg, I think Paris Saint-Germain will be able to defeat Newcastle at the Parc des Princess, home of Les Parisiens. Anyway, Enrique should have given Kolo Muani more opportunities to play as a center forward. However, recently there have been rumors that Assensio is ready to return to the field.
