Tuchel has PSG being an offensive threat all the time. Today, they didn't have Mbappe nor Neymar and had plenty of chances. Rabiot and Verratti are such creative forces.
However, the first half was awful, especially defensively. Sure they didn't have Marquinhos, Kurzawa (out long term) nor Alves, but Diarra simply had never geled with this team. They played much better with Diarra out and Diaby in when they let Rabiot and Verratti cover the D.
ADM is also showing nice form. Meunier with some great crosses, but we know he can do that. How he'll defend is more important.
Tuchel hasn't had a really full healthy team so far and hasn't been able to play his favourite system so far.
This PSG team could hit its full stride in the spring.
