Once again Milan were indebted to the skilful Gerard Deulofeu as the young Catalan inspired the hosts to a comfortable 3-0 win over Bologna.
The visitors couldn't even muster a shot on goal in the entire 90 minutes and rarely troubled the Rossoneri back line.
Bologna's cause wasn't helped by Federico Di Francesco's early injury which saw him replaced by Orji Okwonkwo on the quarter hour.
They battled bravely to a goalless first half but were undone in the 69th minute when Deulofeu opened the scoring, getting in behind a static defence and getting himself booked for an extravagant celebration afterwards.
Keisuke Honda doubled the lead just four minutes later with a wonderful left-footed free-kick that had Antonio Marante beaten all ends up.
Gianluca Lapadula rounded off the scoring in injury time.
