Reading manager Steve Clarke says he "may have to question himself" after his side surrendered a two-goal goal lead in a 4-2 defeat against Fulham.
Clarke's side conceded three goals in six second-half minutes at Craven Cottage on Saturday.
A first defeat in five saw the Royals slip to seventh in the Championship.
"I'll have to assess the game in the cold light of day rather than when I'm emotional just after full time," Clarke told BBC Radio Berkshire.
Reading looked set to extend their recent good form as goals from Lucas Piazon and Orlando Sa put them 2-0 ahead after 49 minutes.
But a brace from Moussa Dembele and strikes from Ross McCormack and Alex Kacaniklic completed a swift turnaround for Fulham.
"Speaking after a game where we've just conceded four goals, I have to question myself and say, 'did I have too many attacking players on the pitch?'" Clarke added. "Did I leave ourselves too open?
"I don't think I did, but maybe individually, the six players we were relying on to be defensively solid were not quite as good as they have been in previous matches."
Reading face Championship leaders Brighton on Saturday as they bid to return to the top six.
