The Schalke goalkeeper believes his knee injury and the form of Lars Unnerstall has meant he has dropped down the pecking order at the Veltins-Arena
The former Valencia man started the season as first-choice, but a knee injury saw him slip down the pecking order, though he made his comeback against Sandhausen in the DFB-Pokal on Tuesday.
"Even if I had made two or three good saves my position would not have been improved," he told Bild.
"I do not think it [who plays in goal] will be decided match by match. Lars Unnerstall will play and I will play in matches against teams like Sandhausen. This has already been decided."
Stevens was quick to urge Hildebrand to stake his first-team credentials by showing the right attitude, citing the example of third-choice shot-stopper Ralf Farhmann, who has not complained about his position.
"When Timo has a problem he must come to me. Farhmann is also disappointed not to be playing but I never hear anything from him.
"Before the season we opted for the experience of Hildebrand but since his injury Unnerstall has done well. The difference between the two is not great."
