Is too early to predict anything. They'll most likely beat Elche today but they still have to face tougher opponents in Bilbao at home and Villarreal before Clasico. Ideally they'll drop 3 points but realistically only Villarreal can probably get a draw.
Clasico is a must win. If they go undefeated by the time they come to Camp Nou and they beat us, we'll be 7 points behind and may as well kiss the Liga goodbye.
They lost La Liga last year because Carlo over-exhausted the team which lead to most of them being injured at the end where they lost points. And of course they were more concerned with CL than La Liga I think Carlo has learned his lesson and with Modric coming back as well as Lucas Silva&Jese to provide backup, its less likely they'll have that type of collapse again.
From their schedule after clasico, Malaga, Celta, and the back to back of Sevilla and Valencia are most likely to see them drop points.
