Ajax have agreed to sell the star midfielder to the Premier League giants for £40m.
The 23-year-old completed a medical on Monday and an announcement is expected early next week.
Van de Beek will be rewarded handsomely at his new club, according to Dutch outlet De Telegraaf.
A new five-year contract will see the Netherlands international take home 120,000 euros a week, or more than six million euros per year.
He will become Ole Gunnar Solskjaer's first signing of the season, but fans hope he will not be the last.
