"The fans have never accepted me and their reaction is something to take into account when thinking about my future," Ronaldo told a news conference.
"I've always said that I don't want to be where I'm not loved. I've never felt at home at the Bernabeu, the fans have never treated me with affection."
The 28-year-old ace said that Real's fans were impatient.
"I've thought about the way I'm treated and spoken with thousands of people, but I have never understood why the fans have so little patience with me," Ronaldo said.
"As soon as I make an error people jeer me," the former Barcelona forward added.
The three-time World Player of the Year said he strived to secure a move to Santiago Bernabeu but he will reconsider a stay by the end of the season given the circumstances.
