Alex Iwobi seemed to not know what formation Arsenal were playing against Brighton as he replaced Mesut Ozil at half-time.
Iwobi replaced Ozil in midfield at half-time and the Nigerian international was captured on television cameras asking team-mate Granit Xhaka what formations Arsenal were playing.
He appeared to ask Xhaka: “What formation are we playing.”
Arsenal would go on to draw the game as the league’s top goal scorer Pierre-Emerick Aubameyang opened the scoring before Jurgen Locadia equalised.
Arsenal reverted from their usual 4-3-3 formation for the diamond set up against Burnley last week.
The Gunners picked up a 3-1 win that night with Ozil playing the full 90 minutes in his preferred advanced midfield role – opposed to out wide.
