The Argentine has impressed whenever he has been called upon, settling into life with the Blues seamlessly after his summer move from River Plate.
Asked how happy he was with his new signing, Pep said: “A lot. I said many times.
“All the headlines are for Erling, and I understand that because of his numbers - but I said in the pre-season in the States that this guy is really good.
“He can play wider with his vision from outside and he can increase our intensity.
“It doesn't matter if he doesn't score goals, he always has chance to score it.
“In the training sessions we see how clinical he is and how fast, and clever he is in those moments.
“We are so happy for him.”
