We consider a class of functional differential equations of the form \begin{equation}\label{eq: FDE} \dot{x}(t)=f(x_{t}) \end{equation} with $f$ defined on an open subset of $C^{1}([-h,0],\mathbb{R}^{n})$, $h>0$. Under certain conditions, which are typically satisfied in cases where Eq. \eqref{eq: FDE} represents an autonomous differential equation with state-dependent delay, the associated Cauchy problems define a smooth semiflow on a submanifold of $C^{1}([-h,0],\mathbb{R}^{n})$. In particular, it is known that at a stationary point of the semiflow there exist so-called local center-unstable manifolds. Here, we discuss an attraction property of these manifolds. More precisely, we prove that, after fixing some local center-unstable manifold $W_{cu}$ of Eq. \eqref{eq: FDE} at a stationary point $\phi$, each solutions which exists and remains close enough to $\phi$ for all $t\geq 0$ converges exponentially for $t\to\infty$ to a solution on the local center-unstable manifold $W_{cu}$.
