Based on what I've seen, something like:
E Martínez; Molina, Romero, Otamendi, Tagliafico; Di María, De Paul, Paredes, Rodríguez; Messi, Lautaro Martínez
Unsure about rightback, that's seemed interchangeable. And I don't know who he's going to use to replace Lo Celso. He filled a kind of unique role as a left midfielder that can play inside. Like Matuidi for France and Juve a few years ago.
