I think it's a bit premature to dismiss Zabaleta on the back of an injury ravaged season (he missed 19 games, or 98 days, through injury), where the whole team played badly. He's had seven excellent seasons prior to his disappointing form last campaign. He's still "only" 31, so I wouldn't write him off just yet. I'm hopefuly Guardiola can get at least another season out of him.
