Benni mccarthy shows off in man united training video
I think there may be some confusion here!
Benni McCarthy is a former South African professional footballer who played as a striker, but he has never played for Manchester United. He played for several clubs during his career, including Ajax Cape Town, West Ham United, and Middlesbrough, among others.
Therefore, it's unlikely that Benni McCarthy would be showing off in a Manchester United training video.
If you're looking for a specific training video or highlight reel featuring Manchester United players, I'd be happy to try and help you with that!
