Missing loads of chances is always a lesser evil compared to barely getting any, atleast with the former there's a hope they will revert to the mean (which Werner has been doing of late all be it more for the national team than us but it's a start), if you barely get any where's the hope? The players behind him were creating chances at will last season, for that reason alone the service excuse doesn't wash. Their finishing can be critisised but creating? Not a chance.
You mention pressing but Rom is the big reason we've gone to shit in that regard, only Saint Maximan and Ronaldo rank lower out of PL attackers. He's not a stylistic fit atall for what Tuchel is/was trying to build and it is frustrating the hell out of me that we've ripped apart a promising system to accommodate him. The get a poacher to finish what we create narrative was far too flawed, in reality you take a man out of the build up and it's showing, big time.
He has to start pushing a goal a game (especially vs the flat track teams) and his goals pushing us into a title race for what we've sacrificed to accommodate him to become even remotely justified.
