Monza can attack quickly through Varela and a wide cross, while Atalanta can keep finding the box through central and wide receivers. The contest should turn on what happens after the first goal or an equaliser. A cleared cross or corner can bring a second decisive contact before either defence settles.
De Ketelaere can find Krstović between Monza's back line, with Rowe or Zalewski giving Atalanta another angle. Monza's Robinson-to-Varela route is live, but their recent games against Napoli and Bologna produced few box shots and they conceded the next decisive contact after drawing level. Birindelli has been ruled out after starting Monza's last match; Atalanta's defensive absences are current, while key attackers had shorter midweek minutes and Scamacca played against Kairat.
Atalanta have the more repeatable supply for a winner once the first score is answered. That's why I'm siding with Atalanta to win.
