Arsenal came from two goals down to draw 2-2 with Standard Liege on Thursday and secure their place in the knockout phase of the UEFA Europa League as group winners.
The Gunners made nine changes to their starting XI but still looked the most dangerous team in a goalless first half in Belgium.
Emile Smith Rowe and Bukayo Saka both saw shots saved by Arnaud Bodart, while Reiss Nelson put a tame header too close to the goalkeeper just before half-time.
Standard Liege took the lead right straight after the break. Samuel Bastien's shot took a heavy deflection off Sokratis Papastathopoulos and beat Emiliano Martinez in the Arsenal goal.
