Or do both like previous years. Why do you think Pep would play Bravo is he not arsed about winning trophies, or does he have good reasons for continuing his policy of the last 3 years.
It's not just the last 3 years, he dropped Neuer at Bayern and Valdes at Barcelona for the domestic cups. Your reserve keeper is an important member of the squad, you keep them happy and in a little bit of nick so they can play if you need them.
