Manchester United boss Sir Alex Ferguson has named two Italian teenagers in his Champions League squad for the second-half of the season.

The club has registered 25 names on the main list, known as "List A" in the competition rules, and an additional five players born on or after 1 January 1987 on "List B".

The absence of Owen Hargreaves through injury and Manucho on loan to Hull City has freed up two spaces on "List A" - these have been filled with Federico Macheda (squad no. 41) and Davide Petrucci (43) from United's reserve-team ranks.

New signing Zoran Tosic is not registered, however, as he is ineligible. The Serbian played - and scored - for Partizan Belgrade in their third qualifying round defeat by Fenerbahce.

United's "List A" squad for the Champions League last 16 is as follows:

GK: 1. Van der Sar, 12. Foster, 29. Kuszczak

Def: 2. Neville, 3. Evra, 5. Ferdinand, 6. Brown, 15. Vidic, 20. Fabio, 21. Rafael, 22. O'Shea

Mid: 8. Anderson, 11. Giggs, 13. Park, 16. Carrick, 17. Nani, 18. Scholes, 24. Fletcher, 34. Possebon, 43. Petrucci

Fwds: 7. Ronaldo, 9. Berbatov, 10. Rooney, 32. Tevez, 41. Macheda

"List B": Ben Amos, Richard Eckersley, Jonny Evans, Darron Gibson and Danny Welbeck.
