Cristiano Ronaldo leaves fans and Rio Ferdinand confused with bizarre video from sauna

Cristiano Ronaldo left fans thoroughly confused this week after conducting an Instagram Live from his sauna, but remaining completely silent.

The Manchester United superstar this week became the first person on the social platform to reach 400million followers, having seen his fanbase grown by a massive 163m over just five months.

Despite his impressive following, he still doesn’t quite seem to have got the hang of Instagram, or at least its live broadcasts.

The 37-year-old began streaming to his followers on Wednesday night as he took in a session in his private sauna, with fans quickly flocking to see what the United star might have to say.

But, much to the bemusement of those tuning in, Ronaldo instead sat silently staring into the camera on his phone, leaving many of 700,000-plus viewers questioning what was going on.

At one stage, the Portugal international panned round to show off his huge garden, although he still remained completely silent.

The strange video even prompted former United team-mate Rio Ferdinand to throw a comment into the mix, asking: “What you doing bro?” along with three laughing emojis.

The live video lasted around 90 seconds before Ronaldo eventually wrapped things up, although users were left questioning what they had just watched.

“Ronaldo has 400million followers on Instagram and he doesn't even know how it works,” one user wrote.

Despite his strange output this week, Ronaldo nevertheless boasts the biggest following on Instagram after reaching the 400m milestone.
