This time PSG is even under more pressure and since they started working with Enrique, they still Enrique couldn't change anything in PSG that's why if he gets bad results in the Chmapnios Leageu there is a huge chance for this coach to get fired even in the middle of this season. Because regardless of the players they lost like Neymar and Messi, but still PSG spent lots of money during the summer.
It is not unusual for PSG to be under pressure, they have lost the highest amount of players this season, if so many players leave the club at the same time then it is natural for the club to perform poorly. If they think that by appointing a quality manager to a club, that manager will improve their performance, they are wrong. A good manager's plan doesn't work if the club doesn't have good players.
Luis Enrique was successful at Barcelona but he has not been successful so far at PSG. I'm not talking about winning the Champions League trophy, I'm only asking Luis Enrique to win League One this season. If Luis Enrique can win the Ligue 1 title for PSG this season with this team, he can certainly consider himself a success in charge of PSG.
