I don't think they're finishing top 4 in a million years. They'll be a Europa League team with 3 pretty big-earners for one place.
It might be so, but i think they will offload on of them in the summer.
Their focus now is to ensure the squad is strong enough to fight for a CL place.
They don't want to be left with 1 LB like some other clubs, and are willing to invest in squad dept.
