Napoli forward Gonzalo Higuain has admitted that he never felt comfortable with his role at Real Madrid.
The Argentine scored over 100 league goals for the Spanish outfit after joining in 2007, but departed to move to Napoli in the summer.
"I constantly felt like I had to prove myself again after already showing what I was capable of a number of times before. Everything goes much better when you have the complete faith of your teammates, coach and directors," Higuain told Cope.
"It was not an easy decision to leave Madrid. I enjoyed many years at the highest level at Madrid, but I needed a new challenge and a change of scenery.
"I am feeling very well at Napoli now. It's a major challenge to try and help Napoli back the heights of the past."
The 25-year-old has scored six times for his new club this season.
