The Reds are now seventh in the Premier League and Benitez was disappointed with their performance against Blackburn.
“I’m a little bit frustrated,” said Benitez “I felt we could win the game.
“In the first half we didn’t play very well but it was a difficult match. They were very direct and we were expecting that.
“After that we changed it with Ngog in attack and Nabil (El Zhar). We were more dangerous and had chances to win. They also had two counter attacks which could have seen us lose. But I think the team played much better in the second half.
“It is a clean sheet and we played better football than the other day, so we are improving, but you have to win these types of games. We had chances, but you need to score from them if you want to win matches.”
The Spaniard was surprised to see striker Ngog’s close range effort hit the crossbar.
“I was convinced it was a goal and after that Kuyt had the rebound but it was well blocked,” added Benitez.
“We were disappointed but in the last minute we nearly conceded a goal. This is football.
“I was pleased with Ngog and Nabil did well when he came on. Hopefully Torres will be available for the next game and maybe he will be on the bench – if everything is okay over the next few days.”
