  Let $f: M \to M$ be a $C^r$-diffeomorphism, $r\geq 1$, defined on a compact
boundaryless $d$-dimensional manifold $M$, $d\geq 2$, and let $H(p)$ be the
homoclinic class associated to the hyperbolic periodic point $p$. We prove that
if there exists a $C^1$ neighborhood $\mathcal{U}$ of $f$ such that for every
$g\in {\mathcal U}$ the continuation $H(p_g)$ of $H(p)$ is entropy-expansive
then there is a $Df$-invariant dominated splitting for $H(p)$ of the form
$E\oplus F_1\oplus... \oplus F_c\oplus G$ where $E$ is contracting, $G$ is
expanding and all $F_j$ are one dimensional and not hyperbolic.
