I thought the shape was interesting, quite similar to ways that Guardiola has sometimes played and what Arteta was trying when he first arrived at Arsenal. 3-2-2-3 in possession, with Chilwell left wing, CHO right wing, and Havertz/Ziyech as the creators playing between the lines on the left and right. It didn't quite come off but it was at least a very different idea than what Lampard was doing and to me it seems like a setup in which Havertz and Ziyech might thrive.
I don't think Giroud is the striker for this setup, but maybe not Tammy or Werner either. Tuchel kept the wing players so wide at times that there was an enormous amount of ground in the middle to cover. That opens space for the creators to burst into but I think to really make it work you need a mobile CF who can drag the defense around then receive the ball to feet and do something useful with it, like play a wall pass back to one of those creators.
This is probably only one tactical set among many that Tuchel tries out. But its definitely not a setup for Reece James. I also wonder where Werner fits. There is essentially no left wing player so its central striker or nothing for him.
