David Moyes says the decision to cancel Sunderland's signing of Yann M'Vila was down to a lack of commitment from the midfielder.
The former France international had been due to re-join the Black Cats on a three-and-a-half-year deal in January, having spent last season on loan at the Stadium of Light.
However, the ex-Manchester United and Everton manager says that M'Vila did not have the necessary "fight" to help Sunderland in their battle against the drop.
"He's a very good player but I only want players here who want to come," Moyes told a news conference
"It was one of those things and that's where we are with it.
