Nico is one of the most versatile players I've seen playing for City.
He's being nurtured as a left back, but his natural position is attacking midfielder (this was evident when he cleverly found space for the Everton goal). In my opinion, as he continues to develop, he could also potentially play as a number six, number 8, or even as a central defender. I say this because he's only just turned 20 and his big frame is still filling out.
It's a huge relief that we didn't cash in and sell him to Chelsea. That would have been an absolute disaster. Now we have retained one of the best young talents I've seen with City.
