We present lattice results that can be fitted only after substituting the Belavin-Polyakov-Shvarts-Tyupkin profile in the instanton-liquid model (ILM) by one based on the Diakonov and Petrov variational methods. This also leads us to gain information on the parameters of the ILM. %K Instantons %K Green functions %~
