Manchester United have been linked with having a mass clearout, as they were a day before Louis van Gaal officially took up his post at the club.
Among the names touted as being suggested as in the firing line by The Mail, is Brazilian defender Rafael da Silva.
A key part of United's 2012/13 title winning side, Rafael struggled with injury last season, saw his twin brother sold to Cardiff, and had to leave the pre-season tour of the US early with groin problem.
Former United player and assistant believes, that despite his fitness problems, the full-back is crucial to United's squad, and should be kept on.
He told ManUtd.com: "I can’t think of any negatives, maybe Rafael coming home injured. I’m hoping he gets a run of games and keeps himself fit for the season.
"We’ve not got that much cover for the right-back position."
With Van Gaal's insistence on playing with wing-backs, Rafael is one of only two men in the squad capable of playing the position on the right, along with Antonio Valencia.
Should Rafael be facing the exit, it would add to speculation United want to sign Colombian World Cup star Juan Cuadrado from Fiorentina, as they have been linked with doing.
Until then however, Neville is correct in that the club don't have enough cover at the position, and Valencia's form has been inconsistent over the past two seasons in any case.
All the Red Devils will be doing, is creating another problem to solve, when there are positions of need in of strengthening in central midfield and defence.
