We show that lattice two- and three-gluon Green functions can be satisfactorily described in terms of semi-classical Yang-Mills solutions after applying some cooling procedure to kill short distance correlations. The same semi-classical behaviour is observed also in the low-momentum regime for the MOM definition of the coupling constant before cooling
