Fans in disbelief at what Cristiano Ronaldo said to a 'lookalike' of him at the Al Nassr game

Cristiano Ronaldo spotted a lookalike in attendance at Al Nassr and shocked fans with what he said to him.

Al Nassr were back in action on Friday night, hosting Al Shabab in the Saudi Pro League at Al Awwal Park.

Ronaldo was the scoresheet, scoring the second goal for the hosts to put his 2-1 up - though Mohammed Al Shwirekh made it 2-2 and ensured the points were shared with a second half strike.

But it was the five-time Ballon d'Or winner's behaviour prior to the game which became a huge talking point online.

As Ronaldo warmed up with his teammates, he could see a doppelganger in the stands wearing a Portugal shirt with the No.7.

Ronaldo immediately spotted the fanboy but then, in footage which went viral, proceeded to insult him.

He said: "Bro, you don't look like me. You don't look like me. You're very ugly."

The fan didn't seem to bothered and told him "You're the best", with Ronaldo responding by putting his thumb up to him and smiling.

But the brutal joke got plenty of reaction on social media, with many stunned by Ronaldo not having any chill.

One fan on X wrote: "Forced smile and pain in the eyes. The guy died a little inside at being called very ugly by the man he clearly idolizes to an extreme level.

A second said: "Imagine glazing a man so hard that you fly to Saudi Arabia, buy a front row seat, do your hair like him, wear his jersey, and talk to him during his warmups only for him to call you ugly to the entire world."

A third agreed: "Calling one of your super fans 'very ugly' is crazy."

A fourth added: "The last part was so unnecessary."

Another commented: "English not being his first language makes it savage."

A final user posted: "Ronaldo keeping it real I guess when you're the GOAT, even the jokes are on another level! At least the fan got a story to tell for life!"

Now in his 40s, Ronaldo has scored 26 goals in 31 games for Al Nassr this season. His side are currently fourth in the Saudi Pro League table after 24 games played.
