Manchester United's raft of academy signings have begun training at Carrington.
Joe Hugill, Logan Pye, and Radek Vitek have started training with the club.
Vitek, 16, has arrived from Sigma Olomouc and is the latest Eastern European goalkeeper to join United's junior ranks after Ondrej Mastny, Matej Kovar and Alex Fojticek. Fojticek was released this month and Kovar is in line for a loan move next term.
The Manchester Evening News says the club is also hopeful of announcing the additions of Marc Jurado (Barcelona), Alvaro Fernandez (Real Madrid), and Isak Hansen-Aaroen before the start of next season.
United are awaiting international clearance for Jurado, Fernandez, and Hansen-Aaroen, who became Tromso's youngest-ever player at the age of 15 years and 319 days earlier this month. A source said: "Hopefully they'll be sorted soon and we can get them confirmed."
