In both cases the clubs are starting from a point far further back. Liverpool in particular, over Spurs in the example you give, have had big money to spend, plus wages, for quite some years. It is very new to have decent money for both Wolves and Everton. Throw into that FFP and neither Moshiri or Wolves can go fully bonkers with a cheque book.
