Lopez admits Barca were in contact two years ago.
"In the summer of 2017, the sports director of Barça ( Robert Fernández) spoke with my agent, who said there was interest in the next season if I had a good campaign," he recalled.
"Everyone knows that I love Barça, I have imagined too many things.
"In my head I thought: that's it, I'm there. And that's when I lost six months, I was lost, I no longer recognized myself."
