Nico is on a season-long loan with Valencia.
He said, "I asked Xavi to go on loan and he understood.
"He wished me a lot of luck and made everything easy for me to go out on loan. I think yes, I had a place. There have been fewer players in the midfield than when I left. But it's not a decision I've made easily.
"I had been living in Barcelona for 10 years and getting out of there is complicated. I had my life, in the team of my whole life. But I think it's the right thing to do and I've gone to a perfect place to develop myself. I think any football team is different to Barça.
"But I suppose that every time you move you need that period to adapt."
