We propose a dynamical mechanism assuming that the effective potential gives a finite value of the chiral condensate if the Polyakov loop vanishes. Using a simple model, we demonstrate that our idea works well for small quark mass, though there should be further constraints to reach the perfect locking of two phenomena.6 pages, 6 figures; minor corrections (explanations brushed up)High Energy Physics - Phenomenologytext
