Why exactly do you blame Pep for this? I'm genuinely interested.
He clearly wanted Laporte and his change of heart at the 11th hour was a major spanner in the works. Further, he wanted Bonucci too but for various reasons that one will have to wait too. It's obvious Pep is dissatisfied with the personnel available but he has what he has.
Smacks of looking for something to blame on Pep.
It's going to take time. It was always going to take time. It was said before he came in that his system takes, for even world class players (ala Barca) a full season to adjust to. It's a completely different style of thinking and play than what comes natural.
There's going to be hiccups, but Pep's revolution is only beginning. Kolarov may never be a tiki taka player, but the young talent we are bringing in is laying the foundation for a Pep team and, again, it only makes sense that show some patience.
