Benitez was furious with officials following last week's loss to Wolves, as Newcastle had DeAndre Yedlin sent off as well as being denied a clear penalty.
"For us, every game is like a final," Benitez said.
"We have to approach every game thinking that one point can make a massive difference at the end of the season. That's the reason why I was upset the other day.
"When you are in control of a game that you can win, everything that happened the other day means for us it is more difficult.
"When you play against teams that are close to you more or less and you are in control, these decisions change everything.
"Now we have to explain to our fans that maybe we are missing three points that could be crucial at the end of the season."
