We derive a strong coupling effective Lagrangian describing Wilson lines coupled to quark bilinears. Wilson line and dynamical quark mass are studied in mean field approximation. A second-order finite-temperature chiral phase transition is found at zero chemical potential μ. For μ≠0 this transition becomes a first-order one.
