  The quantum effective Yang-Mills condensate (YMC) dark energy model has some
distinguished features that it naturally solves the coincidence problem and, at
the same time, is able to give an equation of state $w$ crossing -1. In this
work we further employ the Statefinder pair $(r,s)$ introduced by Sahni et al
to diagnose the YMC model for three cases: the non-coupling, the YMC decaying
into matter only, and the YMC decaying into both matter and radiation. The
trajectories $(r,s)$ and $(r,q)$, and the evolutions $r(z)$, $s(z)$ are
explicitly presented. It is found that, the YMC model in all three cases has
$r\simeq 1$ for $ z < 10$ and $s\simeq 0$ for $z<5$ with only small deviations
$\simeq 0.02$, quite close to the cosmological constant model (LCDM), but is
obviously differentiated from other dark energy models, such as quiesence,
kinessence etc.
