Liverpool captain Virgil van Dijk and manager Arne Slot have highlighted the team's persistent struggles with set-piece defense and offense. The Reds have conceded 12 league goals from set-pieces this season, the most in the Premier League, while scoring only three. Van Dijk noted issues often arise from the second phase of set-pieces and hopes it's not a mental block. Slot views recent wins, despite conceding from set-pieces, as progress but acknowledges the need for improvement in this area.
