If we must play with this formation and Graham must start (which he should) then the only place for Brereton, or any other central striker for that matter, is as replacement for Graham when he tires or is unfit to start.
If Brereton isn't up to that, and that seems to be TM's opinion, then the club has wasted 7M which we will never get back.
All this reminds me so much of the bad old Venky days it makes me weep.
Personally, and feel free to call me old-fashioned, I'd like to see a winger on each wing and two up-front. That way we might see what Brereton can do and other strikers we have for that matter.
You're looking like the last man standing pal!
