It doesn't matter what we do with Martial it won't change the fact that we need to buy 2 players for our front 3.
If you prefer to use Martial as a #9, we will need to buy a LW because Depay has done nothing to prove that he's good enough to warrant a guaranteed spot in our starting XI particularly in attack where we've struggled. If you want to use Martial as on the left, we need a striker because Rooney isn't very good anymore and Rashford is nowhere near ready yet.
I also think if Jose comes in Rooney will be used as #10. He's long admired Rooney and he likes his #10's to be hard working and defensively strong. Perception is reality, and most people still view Rooney this way.
