Manchester United coach Phil Neville has broken his silence over the sacking of David Moyes.
Moyes brought Neville across from Everton last summer.
"He has taken the majority of criticism from outside the club, but if you speak to anyone inside then we've all got to take collective responsibility - from players, the staff, the coaching staff, everybody," Neville told BBC Sport.
"It was really disappointing when David lost his job because I class him as a friend. As a player, I've never experienced anything like that with a manager - maybe once with Kevin Keegan at England, when he lost his job.
"The thing we've all collectively failed on is definitely that we have lost eight games (in all competitions) at Old Trafford this season. That is not acceptable.
"If we played all our games away, then we'd be champions. But we've lost games at Old Trafford against teams that we should be beating. That has been the biggest single failing."
