The Reds lost 2-0 at Chelsea and suffered their third defeat of the season at Stamford Bridge on Sunday.
“I feel the performance wasn’t bad against a good team,” said Benitez. “We worked hard, had some good play.
“Defensively we were good enough. They didn’t have too many chances, so we were defending better. We didn’t have too many chances, which means they’re also a good team.
“But if you make a mistake against a good team, they score. The game was a bit more open after they scored and we had some chances but you have to take those if you want to come back into the game.
“Our target has to be the next game. It’s important to keep calm, keep working, improving. We came up against a good team doing well today, so we have to focus on the next game.
“This year, the top sides will lose points against the other teams, so the main thing is to try and improve and do better each week. We will try to do better against Sunderland.
“We drew a lot of games last season. We lost just two but people were telling me about the draws. Now we’re winning more and losing a few but maybe we’ll have more points.”
“I cannot blame any one of the players,” he added. “We have to be pleased with the team effort.
“We made some mistakes but I was happy with the team effort. That was something we wanted to do. We were right 90 per cent of the time.
“But it’s a long race. Chelsea are very strong but we’ll try to stay as close as possible and see what happens in April and May.
“You will see the top sides losing more points against any team. That’s good for the Premier League, for the competition, but it means we have to keep going. We can’t think about three defeats.
“It’s one game at a time, try to win the next game and improve. That’s it.”
