Brendan Rodgers believes there is an area that needs to be immediately addressed after Liverpool once again conceded from a set piece during the 2-2 draw with Newcastle United at St. James' Park.
Liverpool twice came from behind to salvage a point against Newcastle but Rodgers would have felt they should have made more of their opportunity after Newcastle were forced to play with ten men for nearly 50 minutes.
When Steven Gerrard levelled the score at 1-1 in the first half following Mapou Yanga-Mbiwa's dismissal for pulling back Luis Suarez, Rodgers would have expected his side to go on and claim all three points.
However, the Merseyside club's vulnerability to set pieces was once again on display when Newcastle debutant Paul Dummett converted a free-kick from Yohan Cabatye.
With four of the last six goals conceded coming from dead ball deliveries, Rodgers feels there is a weakness that must immediately be corrected.
"It's something that we need to address, for sure," Rodgers told the Liverpool Echo. "We have to be more aggressive and more switched on. It's concentration.
"The goal at home to Crystal Palace was disappointing. That was a poor goal to give away, but thankfully it never cost us.
"Here, conceding from a set piece put us on the back foot. We were looking forward to the second half at 1-1, and suddenly we were behind.
"It's something for us to work on, but in football there is always something to improve on. At this moment, that is an area for us to look at."
The Reds dropped down to third in the league after the draw against Newcastle but Rodgers is pleased with how his side have performed in the early stages of the season.
After finishing seventh last season they are targeting a top four finish and the Liverpool boss is demanding that his players remain hungry throughout the campaign.
"It was a massive job, coming in here. The opening five or six months were difficult. But since January, I think in terms of points gained, we are in the top three in the country. Hopefully that is an indication that we're doing well and that the club is in order," he added.
"I still think there's a hell of a lot of improvement for us to make, but in the main we're a tight unit, and we just need to keep moving forward.
"There's always a demand for the big clubs. We know that the money we've spent is nowhere near what some of the top four clubs have spent.
"But we're here to compete. Liverpool is one of the great institutions of the game. We're never happy when we don't win, but you have to have a sense of perspective as well.
"To challenge, we need to rely on our coaching, and on bringing players in who are hungry. That's key.
"You need players that are hungry to succeed, players that are at an age where they're not just happy to be a Liverpool player, they want to win as well.
