I have a strong feeling that if Enrique decides to give a more important role to Ter Stegen, Bravo will complain. He already criticized Enrique at the beginning of the season when he wanted to rotate the goalkeepers in la liga.
I get what you're saying Mido, but we can't sign a player until January 2016 and won't change GKs mid-way through the season and besides, Handanovic is a better GK than Bravo so he's hardly a good choice to replace him if he is to become a cup GK.
No GKs want to play minimum amount of games, but Bravo most likely in the end would have to accept being in a such position.
