Well, if he leaves, so be it. Barca needs a #2 keeper who is good enough to start for most top-level teams. Anyone that good is going to want to play more than they will get to as the Barca #2. So, if the backup keeper job gets someone new every few years, that is probably good.
There are about 15 player jobs on this team that will get enough playing time to keep this quality of player happy. That includes one keeper, who will be Bravo for many more years. The squad needs a second keeper, and at least 5 more outfield players, but these are not career jobs, it is really best if these squad players don't stay at Barca too long. They will only get enough playing time when there are injuries, in the pre-season, in early round Copa games and in the second match of Copa and CL knockouts when Barca wins big in the first match. They need to come to Barca after being first-division or junior starters, then if they can't break into becoming core Barca players, they need to move on and be starters, even stars, at some other team. Good examples from prior years were Maxwell, even Yaya.
