Were Arsenal 'lucky' not to concede penalty at Liverpool?

During a Liverpool vs Arsenal match, Liverpool had a penalty claim denied after Arsenal defender Jurrien Timber appeared to pull Alexander-Arnold's shirt — wait, the pull was on Alexander Isak, who plays for Newcastle, suggesting a case of mistaken identity in the broadcast discussion. BBC Sport pundits Kelly Cates, Danny Murphy, and Micah Richards debated whether the referee was correct to wave away Liverpool's appeal and whether the Reds were hard done by the decision. The incident has sparked discussion about whether Arsenal were fortunate to avoid conceding a penalty during the match.
