Liverpool failed to register a shot on target against Arsenal after Opta revised two classifications, Sky Sports reported. It was their first such Premier League home game in 442 matches since records began in 2003, providing new evidence for an analysis of chance creation under Andoni Iraola.
Volume does not establish quality
Attempts initially credited to Ronald Araujo and Alexis Mac Allister were reclassified as a blocked shot and an overhit pass.
Liverpool produced 17 shots worth 1.05 expected goals. Across the season, Alexander Isak scored six league goals from attempts worth 4.35 expected goals. Across nine league rounds, 39 percent of their attempts came from outside the penalty area. They had created seven Opta-defined big chances, a provider classification rather than a count of every opportunity or actual goal.
Wirtz and opponents defending deep
Florian Wirtz created 22 chances without one meeting Opta's big-chance definition. His expected-assists figure was 1.08, illustrating the distinction between opportunity volume and modelled quality.
Sky Sports also said Liverpool spent 27 percent of their attacking build-up facing low blocks. Its analysis argues that conceding first has allowed opponents to protect leads and restrict the space suited to Iraola's quick attacks.
That is a tactical interpretation, not proof of a single cause behind every performance. Liverpool's next challenge is to create shots from more favourable positions and improve their starts. Subsequent data can show whether the quality of opportunities rises alongside their number.
