Emirates hero has second debut to forget at the Robin Park Arena.
Arsenal goalkeeper Jens Lehmann had a game to forget on his second debut at the club as his reserve team lost 2-1 to their Wigan Athletic counterparts.
The 41-year-old came out of retirement to re-sign for manager Arsene Wenger as injuries have depleted him of three first-team keepers two weeks ago.
But the ex German international looked far from comfortable on his comeback and with Manuel Almunia struggling to cut out errors, the Gunners are far from happy.
After a few easy saves, Lehmann did a great impression of Paul Robinson against Croatia, air-kicking a back-pass that narrowly went wide.
But he was back to his vintage best getting involved in an altercation with Wigan defender Adam Buxton following a late challenge.
Arsenal youngster Ignasi Miquel was then dismissed for a professional foul which led to his jkeeper being exposed as Callum McManaman raced clear on 53 minutes before rounding the German and slotting home..
Lehmann nearly embarrassed himself again on the hour as he ventured out of his area only to lose out and it took a fine saving block from Daniel Boateng to prevent a goal.
The German was beaten again seven minutes from time when Joe Holt rounded him to seal the win.
Jeremie Aliadiere also played but was often isolated up front. Arsenal grabbed a consolation when Rhys Murphy stroked home a penalty.
