Are you just having an odd conversation with yourself? You seem to be replying in a contrary fashion to things that haven't been said.
Let me try and simplify it.
Yes I'd love a 6 as good as Grav, in fact better...this goes for all positions at all times. In this particular instance I'd like another midfielder who is better than Endo and more suited to how Slot wants to play. If he ends up spending most of his time on the bench then fine. What is looking to minimise is the risk of burn out or the impact of an injury to a key player that will mess up our chances of winning trophies from this very strong position.
I'm not sat here in a panic about it, but if we could get more depth then great. We can carry an injury to a forward better than we can Grav or Mac.
If you think that's silly then we think differently. That's fine
