I fully agree with your post. I just find it funny that for Fred the "only works hard and runs a lot" is a stick to beat him with, while "at least he works hard and runs a lot" is used to defend Mount. Not that he needs anyone to defend him, he's been OK and basically brings to the table what was expected based on his Chelsea days. I do have a concern that we bought Mount to mould him into a different kind of player that he is, what I always found a wrong approach but time will tell if that worry is justified.
I do expect more from Mount because obviously we might have as well played Fred in those few pre-season games with the same effect, but like I said early on - Mount should be judged after first games against serious opposition away, as it's clear what problem we're trying to solve with this move.
