Bayer Leverkusen and Arsenal played out a tightly contested 1-1 draw in the UEFA Champions League Round of 16, with the German side narrowly edging the possession battle 55% to 45%. The home team's goal-scoring efficiency was their downfall, managing just 3 shots on target from 10 total attempts, compared to Arsenal's 2 shots on target from 6 total.

Leverkusen took the lead in the 46th minute through a well-executed counter-attack, with Robert Andrich finishing off a slick move involving Alejandro Grimaldo. However, Arsenal's resilience shone through, and they were awarded a late penalty in the 89th minute, which Kai Havertz coolly converted to level the scores.

The tactical reason behind Leverkusen's inability to hold on for the win was their passive approach in the latter stages. Despite leading for over 40 minutes, they allowed Arsenal to dictate possession and create more chances, finishing the game with a lower expected goals (xG) figure of 0.85 compared to the visitors' 1.64.

On the flip side, Arsenal's tactical failure was their inability to capitalize on their dominance in the second half. While they had more shots, they struggled to test the Leverkusen goalkeeper, with only 2 of their 6 attempts finding the target. This lack of clinical finishing ultimately cost them the chance to secure a victory on the road.
