The Reds managed a lucky 2-2 draw, following a highly controversial penalty as David Ngog appeared to dive under Lee Carsley’s challenge.
Benitez admits Ngog should not have been given a penalty.
“I think it is difficult to explain [why we didn’t win], we had some many chances, plenty of possession,” he told ESPN.
“But in the end we are talking about the penalty – whether it was or not, maybe it wasn’t, but we deserved to win as we had some many opportunities.
“I was talking to him and he said maybe it wasn’t a penalty, but anyway I would say that with 74 per cent of possession in the first half and how many attempts it is unbelievable that we are talking about a draw in this game.”
