Neville, 35, is unlikely to be offered a new deal after being restricted by injury to just three first-team appearances this season.
While Ryan Giggs, who celebrated his 37th birthday last week, and Paul Scholes are enjoying an Indian summer in their careers, Neville's body is letting him down.

All three are on one-year deals that expire at the end of the season and manager Sir Alex Ferguson said: 'Ryan is unbelievable at 37. His fitness has not changed.
'It is different with Gary. We will have to assess him. He has an injury again and it is difficult when you get injuries all the time in your 30s. That is the advantage Ryan has over Gary.'
Neville's 601 club games puts him fifth on United's all-time appearances list.
