Ok this season, he came mid season, we have a chance for success in 3 comps but for next season board should demand less pragmatism. He is really, really pragmatic coach.
In Dortmund pressure is low, they have their style of play for decades so he was also like this. But when results are much more important and trophies are expected he turns into this.
It was like this in PSG in important games. For example, quarter final of CL against Atalanta he played with: Navas, Kehrer, Silva, Kimpembe, Bernat, Marquinhos, Gueye, Herrera, Sarabia, Icardi, Neymar.
So 4-3-3 where RB is someone who is more CB, CB on DM plus 2 DMs in Gueye and Herrera. Sarabia also someone who played more as AM in Spain. Only after he made offensive changes with Mbappe, Moting, Draxler and Paredes they won the game with 2 late goals. Very often he played with 3 DMs so basically all cards are on Mbappe and Neymar. But we dont have them. Now in Chelsea he almost always puts lineup where you just do not expect us to score more than once. Defensive wing backs, midfielders who never do anything in the final 3rd... Today we had like 2 offensive players. He needs to change this next season so we always have at least 4 or 5 offensive players like City or Liverpool with very offensive full backs.
