We can't overhaul the squad to fill it with players who suit a particular style. The budget isn't there.
This is the damage that Koeman/Walsh wrought. They were given free rein to offload all Martinez's signings and spend hundreds of millions on their own choices. It won't happen again
Silva will just have to get a tune out of his favoured 25 of the current squad, albeit with I suspect a couple of additions. If he can't do it, then Brands will find someone else.
