I read somewhere that the peak year for a goalkeeper is above the average players, so I guess 35 years old is still not too old to play as a goalie. I'd be worried if there's no backup or if he's the starting goalkeeper for the next season, if he's way older than that, though. I guess we can only watch whether he'll prove to us that he can still play at the highest level with minimum mistakes, because that's what has let Barca down for the last few years or so. I wonder if they'll try to secure more options by promoting a GK from their academy or signing another one.
