Arvin Appiah is understood to be set to undergo a medical at Spanish club Almeria.
The 18-year-old is said to have agreed to leave Nottingham Forest in a deal which could be worth £8m.
The Sun report Appiah has been tracked by Manchester United, but La Liga 2 club Almeria have moved quickly to land the England youth international on a permanent deal.
Appiah has played six times for Forest in the Championship since making his breakthrough at the City Ground last season.
He scored on his debut for the Reds in an EFL Cup tie against Burton Albion last October.
He has played once so far this season, helping Forest beat Fleetwood 1-0 in the first round of the Carabao Cup.
The highly-rated teenager is under contract at the City Ground until 2023.
