The three-week international break has not diminished the momentum of the reigning Italian champions.

Even without captain Lautaro Martinez, who was rested until the hour mark after his return from Argentina and Lionel Messi's international farewell match, the titleholders were never threatened.

Capitalising on a poor clearance by Parma's goalkeeper, Petar Sucic opened the scoring in the 13th minute.
