The former Rossoneri midfielder has tipped his compatriot for success in Italy, claiming his capture to be a stroke of genius
The 35-year-old, who joined PSV in May has played alongside the midfielder for the national side and drew comparisons between himself and the Rossoneri's new man.
"De Jong plays almost the same way I do," van Bommel compared to Milan Channel. "He was Milan's best signing of the summer."
"He is also comparable to Gennaro Gattuso in the way he plays to aid both the strikers and the rearguard. I'm sure he'll settle into Serie A quickly as Dutch players tend to do.
"His tactical knowledge is an advantage, while his technique, which can be described as effective, make him an excellent signing for Milan."
De Jong will be hoping to make his debut against Bologna on Saturday night, as Massimiliano Allegri's men aim to make up for their opening day defeat to Sampdoria.
