Jens Lehmann pulled on an Arsenal shirt for the first time since coming out of retirement on Tuesday but had a day to forget as the reserve side lost 2-1 to Wigan at the club's London Colney training ground.
Lehmann has been drafted in as cover due to the Gunners' goalkeeping injury crisis and there have been suggestions he could be called into action after Manuel Almunia's calamitous performance against West Bromwich Albion.
However, Lehmann did not overly impress in the reserve clash with the Latics. He had a horror moment towards the end of the first half, conceded twice, was out-foxed by a young Wigan striker and produced some shaky play in the second half.
After making a couple of comfortable saves, Lehmann had a moment to forget a minute before the break as he air-kicked a backpass and the ball rolled inches wide of the post.
The German made a couple of routine saves in the first half and he was also involved in a spiky moment as he complained to the referee when Adam Buxton appeared to challenge him late.
Jeremie Aliadiere was also handed an outing by Arsenal but he had a tough task up front as he was forced to play for much of the game as a lone striker following the dismissal of Ignasi Miquel for a professional foul.
Being a man down put pressure on Arsenal and Lehmann was left exposed as Callum McManaman raced clear on 53 minutes before rounding the German and slotting home.
Lehmann was almost left with egg on his face an hour into the game, as he ventured out of his area only to lose the ball and it took a fine saving block from Daniel Boateng to prevent another goal.
Wigan continued to dominate with their man advantage and Lehmann was beaten again seven minutes from time as Joe Holt completely fooled the keeper and left him floundering on the floor before slotting home.
Arsenal's second string grabbed a late consolation when Rhys Murphy stroked home a penalty.
