The 4-1 defeat was the fifth time this season Hibs have lost by three goals or more and Hughes' men now look like undoing all their good work from earlier in the season.
The manager has conceded that his squad might not have the attacking strength to outscore opponents and is pondering his options ahead of back-to-back games against the Old Firm.
Hughes stated: "As a manager, I've been looking at it for a while now and maybe we're not as good as we think we are. Maybe I have to set them up to be hard to beat, maybe we're too expansive.
"We're going to have to play a lot better if we want to win matches in the top six."
