Donny van de Beek will discover next week that his life is about to change.
Welcome to the big league mate, because this will be just the start of all the madness.
Van de Beek, 23, might be a Dutch international who has played in a Europa League final and Champions League semi-final with the biggest club in Holland.
But the attacking midfielder is about to step into some of the brightest lights football can shine on an individual - and the pressure on him to handle the glare will be immense.
He will go from being a big fish in a small pond to swimming with sharks at United, where failure is not an option and winning trophies became part of the club's DNA a long time ago.
Van de Beek said it himself after completing his £38m switch to Old Trafford when he said: "I cannot begin to explain how incredible an opportunity it is to join a club with such an amazing history.
"I am now ready to take the next step in my career and perform at the highest level - and there is no higher standard than Manchester United."
He's almost right. There is a 'higher standard' than United and it just happens to have been set in recent seasons by the club's biggest and most bitter rivals, Liverpool and Manchester City.
The challenge now facing Van de Beek is for him to help United bridge that gap and start competing for the Premier League and Champions League titles again.

United have not been crowned kings of English football since 2013, while their last European Cup triumph came more than a decade ago in 2008. The clock continues to tick and is getting louder.
Van de Beek is the latest graduate from Ajax's famed production line to seek pastures new, to see if the grass is indeed greener on the other side.
He will now tread the same path as former team-mates Frenkie de Jong and Matthijs de Ligt following their respective moves to Barcelona and Juventus just over 12 months ago.
Van de Beek won't take the same price tag with him to Manchester, mainly due to the impact of Covid-19 on the transfer market, but he will carry the same burden of hope and expectation on his young shoulders.
Both de Jong and de Ligt have struggled to make significant impacts at Barca and Juve. De Ligt, once a target of United, has found it hard to settle in Turin, while de Jong joined a Barca team in serious decline and finished last season on the wrong end of a humiliating 8-2 hammering from Bayern Munich.
De Jong was asked if he'd spoken to Van de Beek about his move to United and said he hadn't, insisting "did he ask me for advice? No, he can think by himself."
United will hope he can, because he will have to - and fast.
The last Dutchman to join United amid such fanfare was Memphis Depay in 2015 and he lasted two seasons. Old Trafford bosses will be hoping Van de Beek hangs around much longer and justifies all the hype - because they need him to.

Gareth Southgate has had a lot of time to think during lockdown - and it's a good job.
That's because the England boss has some big and difficult decisions to make in the next 10 months, starting this weekend with Nations League games against Iceland and then Denmark on Tuesday.
Like who will be his No.1 goalkeeper heading into the Euros next summer? Will he keep faith with Jordan Pickford or does he allow Nick Pope or Dean Henderson to challenge him?
Looking further ahead, what will be Southgate's best back three? How does he handle a headache like Harry Maguire and is Declan Rice good enough to be a holding midfielder against the best nations in Europe?
But his biggest problem will be accommodating the raft of thrilling attacking talent he now has at his disposal.
How will Southgate fit the likes of Harry Kane, Marcus Rashford, Raheem Sterling, Jadon Sancho, Mason Greenwood, Phil Foden, Mason Mount or Jack Grealish into a system that gets the best out of those he decides to pick?
Kane is the captain and appears undroppable, while Sterling and Rashford have superstar quality. But in theory, so do the rest.
It's a nice problem to have, one countless England bosses of the past have not had the privilege of having, but something has to give.
On paper, England have a side that looks capable of challenging for Euro glory, but we've heard this before and it is now down to Southgate to devise a formula that gets the maximum out of those at his disposal. That's what he's paid the big bucks for.
