Elon Musk has sent shockwaves through social media after tweeting Tuesday night 'he's buying Manchester United' - but it may just all be part of on an ongoing joke.
The world's richest man was urged to buy the Premier League club by desperate fans earlier this year.
Musk, 51, who is the owner of Tesla and Space X and has a net worth of around $265billion (£200bn), submitted a bid in the region of $41billion (£31bn) to buy Twitter in April but United fans wanted him to splash his cash on their faltering team.
