Did Mount remind you of Fred or Eriksen, in terms of positioning, during this pre-season? When Fred/Eriksen played, majority of time they were in withdrawn role alongside Casemiro. Not in even one pre-season game that Mount spent majority of his time with Casemiro.
So I'm still baffled about people saying Mount as replacing Fred and Eriksen. For example, I can't imagine Mount is tasked to man marked KdB next season.
I think Mount will be used mostly as 9/10 hybrid. Bruno will be the deeper 8/10 hybrid or RW. ETH likes Mount energy, pace, and finishing ability. At times last season, he tried Bruno as this 9/10 hybrid but it was unsuccessful because somehow Bruno's finishing was degrading, and the team lost its main creative player. And it is a pretty tasking role.
In short, we actually haven't bought Fred or Eriksen deeper role replacement. Based on pre-season, Mount is most likely not.
