Ronaldo - Dybala
Costa - Pjanic - Can - Berna
Sandro - Chiellini - Bonucci - Cancelo

I've been a critic of the 442 in the past because we got overrun in midfield, but I think this will work better than our 2016/17 version because of a few reasons:
1. Bernardeschi and Costa are better dribblers and have better ball retention than Mandzukic and Cuadrado. It's easier for the midfield to retain possession if the forwards can dribble and shield the ball well.
2. Can is more mobile and better than Khedira.
3. This formation can also be a 4-3-3 with Costa on the left, Dybala on the right, and Bernardeschi as a 10 playing the same role as James Rodriguez.
