He will get his chances.
Pep is too classy to offload him after such a short time at the club, just comming back from a long term injury. Nevertheless, his chances are slim as never before to ever make it into the starting XI. Cuenca impressed a lot more than Afellay in a much shorter time span. Messi, Pedro, Sanchez, Cuenca, Fabregas are all options upfront. Plus Villa next season of course. And possibly Neymar as well. And who knows who else Pep will promote next season. Tello? Rafinha?
If a club like Arsenal wanted him, I'd sell him. Not because I don't want Afellay (I love his shy / humble personality, a schoolboy just like Pep wants it
). But because he deserves more playing time than he will get here. In fact, Arsenal would be perfect (don't they need someone like him anyway, hence the Podolski rumours?). RvP-Afellay partnership.
