Timothy Fosu-Mensah will reportedly become the third youngster to be handed a new contract by Manchester United.
The club confirmed on Monday that striker Marcus Rashford and left-back Cameron Borthwick-Jackson had both committed to deals that have tied them to Old Trafford until 2020.
According to Goal.com, Dutch defender Fosu-Mensah will soon follow suit.
The 18-year-old made his senior United debut in February and went on to feature nine times in all competitions.
The report adds that like Rashford, Fosu-Mensah's fresh terms will be worth in the region of £20,000 a week and will also include an extra 12-month option.
Fosu-Mensah joined United's youth ranks in 2014 after a spell in the Ajax academy.
