Honestly, if this guys can't beat Granada than f...k them. If Gomes, Mathieu and Rafinha are not even good for match agains Granada than they should leave ASAP. Even with this line up we should win easily.
Neymar alone is worth more than all Granada players together so if they can't beat Granada it will be really embarrassing. This is the game they should win without a coach.
If a manager can't rotate in a game like this than what is the purpose of the bench?
