Jordan Henderson admitted Liverpool were left 'very disappointed' after dropping below their own standards in losing 1-0 at Hull City on Tuesday night.
The Reds arrived at the KC Stadium with ambitions of reducing their gap to the top four but drew a blank in front of goal for the second successive match.
That meant Michael Dawson's header past the reach of Simon Mignolet eight minutes before the break was enough to give the home side all three points.
Henderson told Liverpoolfc.com: "It was very disappointing because we set high expectations and we expect to win coming here. We knew Hull would make it difficult.
"They're fighting for their lives down there and they did make it difficult. It was very similar to the West Brom game, where they were sitting in and making it hard to break through.
"Unfortunately, we couldn't break through. We had a couple of good chances to go ahead or get back in the game and we couldn't take them.
"We need to be better in that sense, but also we need to make sure we're not conceding sloppy goals as well. We're very disappointed with the goal."
Henderson himself had several attempts thwarted by Steve Harper between the Hull posts as Brendan Rodgers' team searched for an equaliser.
"We were creating chances, we had a lot of the ball and a lot of possession," the captain on the evening continued.
"Getting to the final third, we got into some really good areas and didn't finish, so we need to be much more clinical in that area.
"If we do that, then we'll be killing teams off, really. We've just got to keep going and hopefully the ball will go in the back of the net soon."
Liverpool have four fixtures remaining this season, with Queens Park Rangers the visitors to Anfield this Saturday afternoon in their next outing.
The manager spoke after the defeat at Hull of the duty to give everything until the end of the campaign - and Henderson echoed the sentiment.
"We've just got to keep going," the No.14 insisted. "Obviously everybody is disappointed with the game.
"We've just got to move on as quickly as possible to the next game, which is QPR at home and hopefully just try to win every game from now until the end of the season and see where we are.
"We've got to keep working. We've got a great bunch of lads who will be very disappointed after tonight. But we've got to go again.
"We've got to lift ourselves because we know at the weekend QPR will be right up for it. It will be a difficult game.
"But we set high expectations of ourselves and we expect to be winning games like this. The next game is important so we'll need to make sure we bounce back."
