In my view we can manage with our current defence crop for another year. If Ancelotti thinks Gabriel is worth pursuing, fine.
I'd rather put everything we have into midfield 2 x CM, RM, and another forward if we have resources and depending who we can flog. We must keep Richarlison and keeping Digne would negate the need to replace him, when the need is far more obvious elsewhere.
Bernard seems the obvious one to get off the wage bill, even a modest fee would represent profit and there would be takers on the continent for him I think.
We should also maximise frees and loans where possible. If we are targeting quality over quantity, then leave that to the paid transfers, and allow a small proportion of the budget to pad out the squad with an extra player or two, if required.
