Manchester United are expected to confirm the signings of defenders Marc Jurado and Alvaro Fernandez and forward Isak Hansen-Aaroen.
The Spanish defender will move to the Red Devils youth set-up once final clearance has been received. The 16-year-old Jurado and the 17-year-old Fernandez are joining from Barcelona and Real Madrid respectively.
Tromso forward Isak Hansen-Aaroen, who turned 16 last weekend, is also joining United. The Norwegian last month became their youngest ever player when making his debut at the age of 15 years 319 days, with the club now awaiting paperwork to complete the deal.
However, Manchester United midfielder Fred has been linked with a move to Galatasaray. The Brazilian has hit back from his slow start at Old Trafford and impressed in United's midfield last season.
Sport Witness report that Turkish giants reckon they can persuade him to move. But it is still unclear whether Ole Gunnar Solskjaer would be prepared to let the 27-year-old leave with a big squad needed for the Champions League next term.
