Let $M$ be a compact Riemannian manifold with no conjugate points such that its geodesic flow is expansive. We show that there exists a local product structure in the unit tangent bundle of the manifold which is invariant under the geodesic flow.In particular, we have that the set of closed geodesics is dense and that the flow is topologically transitive.
