Let me give my take. I agree that Tuchel was at fault. But completely? No. Leonardo didn't bring in any good replacements. Half of the first team players were out. No authority over anything for the coach in sporting sense. But Emery and Blanc were given everything they wanted. https://twitter.com/PSGTalk/status/1318661750418407424

Apart from this, let's come to the individual performances. There is something wrong with Mbappe and Neymar. Pressure games happen, they choke. Like big time. They haven't scored in UCL for a while now. This is a big concern since they are the superstars

The other reason which somehow coincides during Ucl games is the squad. Right now, Verratti, Marquinhos, Paredes, Bernat, Kehrer, all first teamers are out. The depth is so shallow that Psg, a team with so much money has to play the likes of Kurzawa.

In the end, if Psg wants to win trophies than they have to let go of with this different treatments with different personalities.Back the coach,don't let superstar control everything,bring inadequate players, make a good sporting project which is based AROUND manager, not player
