Milan won 4-0 as Suso curled in a free kick, set up a goal for Mario Pasalic and performed admirably throughout.
“Everything went perfectly today and we had the temperament of a great side," Montella told Mediaset Premium.
“Considering the chances created, we should've scored a lot more, but I am satisfied anyway."
He added: “I want to go into Europe, regardless of what Inter do. They are an opponent like any other. It's a tough fight for Europe and will probably only be decided in the final round of the season."
