Liverpool have never failed to reach the last 16 under Benitez's management, but they are in grave danger of that eventuality now with qualification from Group E out of their hands after the midweek draw in Lyon.
They must hope that Lyon win their next match away to Fiorentina, and that Liverpool win their final two group games to produce the "miracle" Benitez admits they need now.
He said: "I spoke to Christian Purslow (Liverpool's managing director) the other day about the finances.
"The first thing, though, is that we have confidence we can still reach the last 16 of the Champions League this season.
"But whatever happens, the budget was done for this season based on us only qualifying for the group stages. And we did that, that is complete. Whether we can still bring in more money, we will wait and see."
