Gaitan is , tbh... call up el pity martinez, try some new, young blood... Biglia and Lamela are stealing a spot right now... Pratto is a sub at most... Rojo needs to go...
If you want to go full Bilardo, something like this would work:
Romero
Zabaleta - Otamendi - Cuesta - Funes Mori - Mas
Dybala - Mascherano - Pity Martinez
Messi
Icardi
If you want a more offensive 4-3-3:
Romero
Zabaleta - Otamendi - Funes Mori - Mas
Banegas - Mascherano - Pity Martinez
Messi - Icardi - Dybala
If you want a more defensive 4-3-3:
Romero
Zabaleta - Otamendi - Funes Mori - Mas
Banegas - Mascherano - Kranevitter
Messi - Icardi - Dybala
A 4-4-2 to hold on to the ball:
Romero
Zabaleta - Otamendi - Funes Mori - Mas
Banegas - Mascherano - Kranevitter - Augusto Fernandez
Messi - Icardi
Not even sold on Romero either, tbh, but I can't think of another keeper at the moment.
Di Maria needs not to be called up for a few games, so he gets the picture he's not a lock to make the team and needs to work his ass off again.
