The Reds will have to play Reading again after drawing their third round FA Cup game yesterday but after the match Benitez admitted things could have been worse.
"I am disappointed because we didn't want to play more games but it was a tough game," he told reporters after the final whistle.
"We have another chance at Anfield and hopefully we can play a little bit better.
"You could see it was a difficult game. They were pushing and working very hard from the beginning until the end, so we had to do our job.
"When we conceded, we knew it would be more difficult, but after we scored we had some chances, and they did too.
"They played really well. To play Liverpool live on television was a massive boost for them and they did really well.
"Credit to them but we are still in the competition and to play again at Anfield will hopefully be good for us.
"I thought we had some good movements and some bad movements, but credit to them as they worked so hard. It was difficult and also the pitch didn't help the game."
