Sunderland boss Chris Coleman admits he "fell flat on his face" on his debut in the Stadium of Light dugout after Reading took all three points from a 3-1 victory.
The Royals ensured the Black Cats' wait for a home win was extended to 21 matches despite the lift of having Coleman in charge on Wearside for the first time.
David Edwards scored the first goal eight minutes after half-time before Mo Barrow added two more in the 68th and 71st minutes to make it one defeat in seven for Reading - even though Lewis Grabban stroked in a penalty with 14 minutes remaining. Callum McManaman was dismissed for the hosts.
Sunderland remain in the Championship relegation zone.
