McManaman claims Benitez's options prove money has been wasted at Goodison Park in recent years, and insisted the club cannot continue to rely on Dominic Calvert-Lewin and Yerry Mina, who have struggled with injuries this term.
"Somebody, I don't know who it is, has spent a lot of money at Goodison," said McManaman afterwards. "The new owners have come in and spent a lot of money.
"You cannot be relying on Dominic Calvert Lewin when things start going wrong or Yerry Mina who is a good centre defender.
"When you looked to the bench today and what they could bring on there was nothing there. So who's wasted this money on these players? Because someone has to be held accountable for it."
