With Marchisio as the DM, the starting midfielders should definitely be Pogba and Pereyra.
While Marchisio is out, if you put a guy who can't defend like Hernanes as a DM, Sturaro has to be there to compensate.
Ideally Lemina can work as a true DM, allowing Pereyra to go back to the lineup. He's one of our best players, should be a starter.
