We analyze the $\eta N$ interaction using a coupled channel separablepotential model that implements the chiral symmetry. The model predicts an$\eta N$ stattering length $\Re a_{\eta N} \approx 0.7$ fm and in-mediumsubthreshold attraction most likely sufficient to generate $\eta$-nuclear boundstates. The energy dependence of the $\eta N$ amplitude and pole content of themodel are discussed. An idea of the same origin of the baryon resonances$N^{\star}(1535)$ and $N^{\star}(1650)$ is presented.
