The combative midfielder is pleased with the changes under the club's new head coach and has urged his team-mates to remain focused
The Dutchman replaced Massimiliano Allegri as the man in charge at San Siro last week and guided the Rossoneri to a 1-0 win over Hellas Verona on Sunday courtesy of a Mario Balotelli goal.
"We’re playing a more attacking system now and that’s clear. It’s a different approach," De Jong told the official Milan website.
The holding midfielder then acknowledged that Milan still have a long way to go, though, and stressed that they must remain focused.
"Clarence Seedorf was always my idol.
"He said there’s a long way yet to go and we have to focus on the next games. At the moment, the Coppa Italia is the best way to get back into Europe next season and we have to do it.
"We’re very focused."
Milan remain 11th in the Serie A table with 25 points from 20 games.
