This query identifies teams that won more duels (i.e., won more ball possession challenges) but ended up losing the game. This can indicate a situation where the team was physically dominant in the midfield but inefficient in converting their opportunities into goals. Understanding such matches can help in analyzing areas where teams with strong ball-winning abilities might struggle, such as in converting possession into meaningful attacks or handling counter-attacks from their opponents.
