Ronaldo established himself as one of football's greatest players over the last decade and has been constantly been targeted by the boo-boys during his time at Manchester United and Real Madrid.
Speaking at the Globe Soccer Awards where has named the Player of the Century, the Portuguese star admitted that playing without supporters is boring.
"For me, I have to be honest, to play in an empty stadium is boring, in my opinion," Ronaldo said, as per Goal.
"We, the players, respect all the protocol and health is the most important thing of all, of course, but I don't like it, to be honest.
"I do it first of all because I love football. My passion is always football. I play for my family, my kids, my friends, the fans. But I don't like it, to be honest. It's so weird.
"I like it when people boo Cristiano. When I touch the ball they 'boo', I like it. I hope in 2021 they can change the rules and we can see the stadiums full of people."
