The social media star – real name Darren Jason Watkins Jr – was streaming in Amsterdam when he was mobbed by fans.
Speed and his entourage found themselves on a boat amid the fan frenzy when police showed up to question him.
And that is when the Ronaldo super-fan told cops he was related to the Manchester United legend.
He said: “Wait, listen, I’m like a famous football player, I’m a famous streamer, you know me. Cristiano Ronaldo?
“Yeah, that’s my… I’m kin to him, and I do YouTube, and all these Netherlands, German and Dutch people coming after me, ‘Speed! Speed!’
“I’m like, calm down, calm down, get off the way, get off the way. And they’re just coming out at me, like basically I’m just like, I’m like Ronaldo’s son, basically.
“Like, I swear to God, like I got pictures.”
Speed shot to fame by playing FIFA online and streaming it while becoming synonymous for idolising Ronaldo.
The gamer has met his hero before and travelled to Germany for Euro 2024 to support Ronaldo in person.
But he launched a foul-mouthed rant at police when he was stopped from meeting Ronaldo before a match.
The American was sat in VIP seats as Roberto Martinez’s side came from behind to seal a dramatic win 2-1 win over the Czech Republic.
Speed, 19, live streamed his reaction to the game for the entire 90 minutes.
And after the final whistle, the teen with 25.5million YouTube subscribers went downstairs to meet his favourite players.
Speed waited in the players’ car park for an hour and a half and was on his phone texting Portugal star Rafael Leao, who agreed to meet him.
But disaster struck for the influencer as he was escorted away by cops.
They told him all fans in the area had to leave, with his claims of being in contact with Leao falling on deaf ears.
Speed was taken outside and told to wait there – only for the Portugal team bus to then drive past.
He shouted Ronaldo‘s name at the coach as it zoomed out the Leipzig Stadium before turning to the camera as he looked on devastated.
Speed then raged: “See I missed them because of the f***ing police officers.
“I’m leaving bro. All these f***ing police officers. I just missed them because of these officers.
“Stupid f***ing officers. He literally told me to wait right there.”
