I see no harm in keeping him as a squad player, even if we sign a couple of midfielders. I doubt he's on huge wages, and while he's under contract we might as well have him in and around the squad. It's not like we're going to get a substantial fee for selling him.
The point about a Moyes pre-season is interesting. Do we think Moyes will bring an extra level of fitness to our current players? If so, a fit Anderson would be an interesting prospect.
If his Everton sides are anything to go by, most definitely.
