I don't know when will people understand that at the current state Pedro is irreplacable for the team. If we didn't have a transfer ban, than it would be worth a thought, maybe. Even then, he's a Barca kid, one of the few succesful, he's one of those players who should be kept happy.
August - January with attack options of: Messi, Suarez, Neymar, Sandro and Munir is not good enough. Adding Pedro on that list would help A LOT.
Besides, players don't develop unless they have competition. Messi and Suarez don't need to develop anymore, yes BUT Neymar does and his weakness is Pedros strenght - teamplay.
So in conclusion, losing Pedro would be a disaster right now, and even in January. He's a Barca boy who has given a lot to this club. Needs more respect.
