Manchester United seem to have edited the audio from Casemiro's Old Trafford unveiling, with the real sound from the clip emerging online.
The Red Devils paraded their latest signing in front of the Old Trafford faithful ahead of Monday's Premier League clash against Liverpool.
He received a thunderous reception from the fans packed inside the stadium, with Man United posting the clip on social media.

But it appears they've edited the audio from the video, with chants of "UNITED, UNITED, UNITED!"
@FinFtbl, however, shared a video of Casemiro being brought out to the pitch and the sound is completely different to the clip Man United shared on Twitter, accompanied with the caption: "Audio matches up eh lads?"
The chant of "WE WANT GLAZER OUT, WE WANT GLAZER OUT" can be heard from the fan's video.
Man United fans held a protest against the club's ownership prior to their big win over Liverpool.
Casemiro, meanwhile, spoke for the first time since signing for the club and the five-times Champions League winner expressed his excitement over the move.
"There's no doubt I'm really excited. I've been very warmly welcomed," said the 30-year-old.
"I've already felt that special affection from everyone towards me and of course that's really important.
"I felt that great affection from the moment I arrived and I think it's a new challenge. I'm absolutely delighted.
"I feel like I'm 20 or 18 years of age, I'm raring to go, I'm excited to be amongst my teammates, playing in the stadium and I think that it's just huge excitement and I'm absolutely delighted."
The Brazilian is available for selection and could make his Man United debut on Saturday against Southampton.
