You like a player so much you don’t use him? Yeah that makes sense. Especially a player you have a chance of buying.
Or maybe he’s just not impressing in training over others. The most simple and reasonable explanation.Just speculating here. Arteta has more information. There is a reason he is not using him. Maybe its injury still affecting him? Maybe Ceballos has told Arteta he don't see him self signing for us next summer?
