Nico joined City last January from Porto.
“I think Pep is the coach who has improved me the most,” said Nico to City's website. “And not just me, but all the players that I see – many of us have come through and you can see the progression.
“He’s incredible, especially because he makes you understand the things you do, which I think is important.
“He gives you instructions, he explains why, and he teaches you the reason.
“(In terms of adapting to the Premier League) The truth is that it has been an experience, and it has been an incredible experience. I couldn’t imagine being in this situation right now.
“I have learned a lot. I think I have improved a lot in many concepts, physically, tactically, in every way.
“Competing in this league every three days, as we are doing, requires you to improve and adapt and grow in every way.”
