Aldridge recently wrote about the team's struggles, stating that they need to improve their ability to keep a clean sheet.
He believes that this is the main difference between Liverpool and Arsenal, who are also competing in the title race.
Aldridge notes that Arsenal may not be the most exciting team, but their defensive solidity gives them a chance to win games.
He is worried that Liverpool's vulnerability at the back and inability to press the opposition could hinder their chances.
Aldridge suggests that the team's forwards are not doing enough to press the opposition, which is allowing them to create scoring opportunities.
This lack of defensive security is a concern for Aldridge, who believes it could affect the team's overall performance.
