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