The lad has put some decent performances in as well as poor ones, not to mention nearly 8 years of service, so why not treat the lad with a bit more respect?
It's for the club to make that decision. Any fan doing it is out of line. We don't own the club or the players. We watch them play, and nobody forces us to do so, so not really our place to be telling players, especially ones as loyal as Neville "In no uncertain terms" to go.
If you support the club, support the whole club. His standard has never been that of the very best, but some of the criticism is a bit over the top, and no need for it.
