It was news no-one expected, and for a while it sent social media and the football world into a frenzy.
Cue pandemonium on the social network, with the American’s tweet receiving more than 400,000 likes.
Also, I’m buying Manchester United ur welcome

It has been a painful start to the new season for United.
They are bottom of the Premier League after two defeats, star player Cristiano Ronaldo could leave, while new signings are failing to materialise.
Their fans are restless, and earlier this week the Manchester United Supporters Trust said it will “demand answers” from those running the club after a “humiliatingly bad” start to the season
The club has been in decline since Sir Alex Ferguson retired as manager in 2013, and fingers have been pointed at the Glazer family, who have owned the club since 2005.
There have been multiple protests against the Glazers’ ownership in recent years – including one in May 2021 which caused the Red Devils’ match against Liverpool to be postponed.
United fans are planning another protest against the American family during their latest meeting with their bitter rivals on Monday.
Some fans welcomed Musk’s interest in their club, which was valued at $4.6bn (£3.8bn)
Former Liverpool and Netherlands winger Ryan Babel saw an opportunity.
Now i need to buy Man United stock got dammit lol

Other fans wondered what a club run by Musk would look like, given he also owns rocket company SpaceX and electric car company Tesla.
But the thought of Musk branching out into football was short-lived.
Musk, who has more than 103 million followers on Twitter and is currently trying to unwind his $44bn (£36.3bn) offer to buy it, later clarified he was just joking.
Meanwhile, United did not comment on the speculation.
Just as the UK was waking up, Musk was asked if he was “serious” about the bid, and replied at 5:34 BST: “No, this is a long-running joke on Twitter. I’m not buying any sports teams.”
He added: “Stand-up is my side-hustle.”
But it turns out he is fan of the Red Devils, tweeting: “Although, if it were any team, it would be Man U. They were my fav team as a kid.”
Are you serious?
