I agree he did. But we have to consider the context. Pre-seaon Girona. Even Roberto looked much better than usual.
I am not opposed to Pjanic staying though. He had a hair transplant so he might feel more comfortable coming season.
Of course, its pre season, Pjanic didnt play in Euro, sparing teams are not on Barcas level...Is Pjanic good for starting 11? No he is not...but he most certainly is for Bench and he is better than some players that Koeman keeps giving chance.
