Mikel Arteta's decision to start Bukayo Saka backfired as Arsenal were beaten 2-1 by French strugglers Lens in the Champions League - a stark reminder of the difficulty of any game at this level.
On an uncomfortable night for the Gunners boss, Saka was forced off on 34 minutes, shortly after Adrien Thomasson's fine strike cancelled out Gabriel Jesus' unerring finish into the bottom corner, and in his absence the visitors limped to a deserved defeat.
