In terms of scheme and possession of the ball they are not lacking because PSG still always dominates in every match they do, it's just that the final solution still cannot be said to be good. They still need to maintain the chemistry of the players for this because sometimes poor finishing occurs because their attack line is not yet integrated.
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.
