I agree. 343 is most suited for us. So why change? But very often we win games with some wonder goal or set piece or penalty... Defense in perfect but offensive part must be much better.
Tuchel has to be less pragmatic. We saw in basically every game that CHO offers much more offensively then James but he picks the later because he is so pragmatic and because of the wrong reasons, it is just not worth it.
Mount is MF and I would not call his position number 10 under Tuchel. It is something between number 10 and a winger. I am sure if you look at heatmaps he plays pretty much the same role as Willian. But Tuchel does not expect the same from him as from other 2 attackers. Kai or Puli if do not deliver in the final 3rd in terms of goals in one game after previous good game are instantly on the bench. Very high standard. But Mount for example now has 3 games in a row with absolutely nothing but still he will start last two games. Why? Because Tuchel picks him every time for pragmatic reasons not related to input in the final 3rd. When we start with James, Chilwell and Mount I say we have 9 defensive players and just 2 offensive (which has to deliver if not, they are dropped). But if we go with lets say Pulisic, Werner, Havertz as front 3 and CHO as RWB that is 4 attacking players. So I really hope for next season we go with the later because I dont think in the long run we can survive with this. City always have 5 players on the pitch who could do danger.
