Dwayne ‘The Rock’ Johnson looks unrecognisable as Man Utd legend in Halloween costume – but can you guess who it is?

HOLLYWOOD superstar and WWE icon Dwayne 'The Rock' Johnson left fans stunned after dressing up as a Manchester United legend for Halloween.

If you haven't guessed already, the player in question is none other than David Beckham.

The Rock took to Instagram to share a picture and video of his impressive costume.

Fans took to the comments to react, with one person writing: "David Beckham If he chose the gym instead of Manchester United."

Another added: "The Rock wearing a Manchester United jersey is the video I never knew I needed!"

While a third joked: "Costume is complete when you take free kicks like he did 😂."

Beckham also shared an image of Johnson's costume on Instagram and commented: "And the winner is @therock 🎃 looking good man I know what I’m going as next year 💪🏼 😃."
