Manchester United are yet to agree new contracts with young defenders Paddy McNair and Tyler Blackett, according to reports.

The duo have broken into the Red Devils first team this season following injuries to senior defenders Jonny Evans, Phil Jones, Chris Smalling and Marcos Rojo.

According to BBC Sport, however, United have refused to discuss whether they intend to make further offers to the youngsters.

McNair and Blackett's contracts expire at the end of the season, and as of January 1, they have been free to talk to other European clubs.
