What would happen to Pellers if we don't get out of our group?

Now guys before I get the "OH MY DAYS WE LOST ONE GAME STOP QUESTIONING OUR MANAGER" I'm not, Pellers has proved me wrong many times and has changed my first view of him. I'm not calling for his head. The thing is though if we don't get out of our group, which is possible seeing the way Juve turned the game on it's head and Sevilla brushed away Munchengladbach, what do you think would happen if we failed to get out of our group?
