  We consider a BRST invariant generalization of the "massive background Landau
gauge", resembling the original Curci-Ferrari model that saw a revived interest
due to its phenomenological success in modeling infrared Yang-Mills dynamics,
including that of the phase transition. Unlike the Curci-Ferrari model,
however, the mass parameter is no longer a phenomenological input but it enters
as a result of dimensional transmutation via a BRST invariant dimension two
gluon condensate. The associated renormalization constant is dealt with using
Zimmermann's reduction of constants program which fixes the value of the mass
parameter to values close to those obtained within the Curci-Ferrari approach.
Using a self-consistent background field, we can include the Polyakov loop and
probe the deconfinement transition, including its interplay with the condensate
and its electric-magnetic asymmetry. We report a continuous phase transition at
Tc ~ 0.230 GeV in the SU(2) case and a first order one at Tc ~ 0.164 GeV in the
SU(3) case, values which are again rather close to those obtained within the
Curci-Ferrari model at one-loop order.
